[adult accessory mesothoracic neuromere on adult VNS template, Court2018; adult accessory mesothoracic neuropil; computer graphic; adult VNS template - Court2018]
Region of dense neuropil located at the interface between the mesothoracic neuromere and the prothoracic neuromere, ventral to the tectulum (Court et al., 2020). It mostly contains sensory afferents from the wing and notum that enter the central nervous system via the anterior dorsal mesothoracic nerve (Power, 1948; Court et al., 2020).
The adult antennal lobe is a bilaterally paired synaptic neuropil domain of the deutocerebrum lying in front of the protocerebral synaptic neuropil domains. It is divided into approximately 50 glomeruli and is clearly separated from adjacent neuropil domains by an extensive glial sheath. The two antennal lobes are connected by the antennal commissure and receive olfactory receptor neuron axons from the antennal nerve and subesophageal tract. It is also connected to the antennal lobe tracts and the broad root.
Glomerulus of the adult antennal lobe, defined by the output terminals of specific sets of sensory neurons (Bates et al., 2020). Many former ‘compartments’ now modeled as glomeruli in their own right following Bates et al. (2020) EM paper term usage.

[adult antennal lobe on adult brain template JFRC2; computer graphic]
Adult sensory region of the subesophageal zone that develops from the larval anterior ventral sensory compartment (Kendroud et al., 2018). It receives fibers from the anterior root of the maxillary-labial nerve and fibers of the pharyngeal nerve (Kendroud et al., 2018).
Butterfly-shaped region of the posterior adult subesophageal zone (Munch et al., 2022). It has three subregions, whose activity in response to yeast stimulus is modulated by internal metabolic state (Munch et al., 2022). Munch et al. (2022) do not define this as a motor or sensory region.
A midline crossing complex of the synaptic neuropil domains of the adult brain: the ellipsoid body, the fan-shaped body, the three paired noduli, the asymmetrical bodies and the protocerebral bridge. It is closely associated with another paired synaptic neuropil domain, the lateral complex. It lies in the middle of the brain between the pedunculi of the mushroom bodies and is bounded ventrally by the esophagus, dorsally by the pars intercerebralis and laterally by the antenno-glomerular tracts. Some authors’ use of the term ‘central body’ excludes the protocerebral bridge, some usage also excludes the noduli, some exclude the lateral triangles, and historically it has been used to refer to the fan-shaped body alone (Hanesch et al., 1989).
[adult central complex on adult brain template JFRC2; computer graphic]
Adult sensory region of the subesophageal zone that develops from the narrow anterior (tritocerebral and gnathal) region of the larval central sensory compartment (Kendroud et al., 2018). It encompasses the antennal mechanosensory and motor center at its anterior end, containing the axon terminals of Johnston organ neurons entering via the antennal nerve (Kendroud et al., 2018). At its posterior end, it receives axonal projections of thoracic and abdominal sensory neurons, which enter the subesophageal zone via the cervical connective (Kendroud et al., 2018).
A thin, bilaterally paired synaptic neuropil domain that wraps around the medial lobe of the mushroom body. Many neurons in this domain enter the lobes to form extensive connections with Kenyon cell fibers. The name crepine is used in French cuisine to refer to a slice of meat wrapped around some delicacy. The posterior region of the crepine corresponds to the dorsal part of the inferior dorsofrontal protocerebrum (IDFP) of Chiang et al., (2011) (Ito et al., 2014).
Layers 6-9 of the fan-shaped body (Hu et al., 2018; Kacsoh et al., 2019). This region is involved in sleep regulation (Donlea et al., 2011; Donlea et al., 2014; Qian et al., 2017; Yurgel et al., 2019).
Any adult antennal lobe glomerulus (FBbt:00067500) that receives input from some hygrosensory neuron (FBbt:00005923).
Small region of the adult mesothoracic neuromere connecting the two giant fiber neurons across the midline, proximal to their lateral axonal bend (Allen et al., 1998). Several neurons that connect to the giant fiber neuron(s) via gap junctions do so in this region (Kennedy and Broadie, 2018).
Medial subregion of the adult borboleta region (Munch et al., 2022).
A bilaterally paired synaptic neuropil domain of the adult brain with a roughly pyramidal shape that is located inferior-lateral to the ellipsoid body and anterior-inferior to the bulb (lateral triangle). It lies behind the antennal lobe and in front of the ventral complex. The LAL corresponds to part of the anterior superior part of the vmpr of Otsuna and Ito (2006) and to the ventral part of the inferior dorsofrontal protocerebrum (IDFP) of Chiang et al., (2011) (Ito et al., 2014).
Dorsolateral horn-shaped synaptic neuropil domain of the adult protocerebrum that houses the terminals of various antennal lobe projection neurons (Ito et al., 2014). It is not separated from other neuropils by a glial sheath, but by the extent of arborization and synapsing of these antennal lobe projection neurons (Ito et al., 2014).
Ventral lobe present in each thoracic neuromere of the adult ventral nerve cord (Namiki et al., 2018; Court et al., 2020). Somatosensory neurons of the leg terminate in parts of this neuropil (Tsubouchi et al., 2017).
Synaptic neuropil subdomain of the adult subesophageal zone that houses the dendritic terminals of motor neurons (Munch et al., 2022).
Bilaterally paired neuropil structure situated postero-dorsally in the protocerebrum that functions in olfactory associative learning and memory. The mushroom body is divided into: the calyx, which is closest to the cell body rind and receives sensory interneuron afferents; the pedunculus, which is a thick axon bundle extending from the calyx to the base of the lobes; and the mushroom body lobe system, which consists of a vertical branch composed of two intertwined lobes (alpha and alpha’) and a medial branch consisting of three parallel lobes (beta, beta’ and gamma) (Crittenden et al., 1998; Ito et al., 2014).
Subregion of the adult mushroom body vertical lobe (Ito et al., 2014). It is composed of the vertical branches of alpha/beta Kenyon cells (Ito et al., 2014).
Subregion of the adult mushroom body vertical lobe (Ito et al., 2014). It is composed of the vertical branches of alpha’/beta’ Kenyon cells (Ito et al., 2014).
A subregion of the alpha’ lobe occupied by the vertical lobe projecting branches of the neurons composing the mushroom body beta’’ lobe of the adult brain. Via Golgi impregnation and immunostaining, Strausfeld et al., (2003) identifies this highly taurine-immunopositive, aspartate-immunonegative band. However, Tanaka et al., (2008), using an enhancer trap screen, suggest that the neurons composing the alpha’’/beta’’ lobe should be regarded as a subpopulation of the alpha’/beta’ anterior neurons.
Subregion of the adult mushroom body medial lobe (Ito et al., 2014). It is composed of the medial branches of alpha/beta Kenyon cells (Ito et al., 2014).
Subregion of the adult mushroom body medial lobe (Ito et al., 2014). It is composed of the medial branches of alpha’/beta’ Kenyon cells (Ito et al., 2014).
A narrow division lying between the gamma and beta’ lobes of the adult brain. Axons innervating the beta’’ lobe have axons innervating the alpha’ lobe front surface. Via Golgi impregnation and immunostaining, Strausfeld et al., (2003) identifies this highly taurine-immunopositive, aspartate-immunonegative band. However, Tanaka et al., (2008), using an enhancer trap screen, suggest that the neurons composing the alpha’’/beta’’ lobe should be regarded as a subpopulation of the alpha’/beta’ anterior neurons.
A small subregion of the adult mushroom body that protrudes from the anterior-dorsal edge of the calyx into the superior lateral protocerebrum (SLP) (Ito et al., 2014). It contains the terminals of the alpha/beta posterior Kenyon cells (Tanaka et al., 2008; Ito et al., 2014; Aso et al., 2014) and it is not separated from the SLP by a glial sheath (Ito et al., 2014). It receives mainly visual input with little, if any, olfactory or gustatory input (Li et al., 2020). Previously named the accessory calyx, this was renamed to the dorsal accessory calyx to distinguish it from the ventral accessory calyx (Aso et al., 2014).
Subregion of the adult mushroom body medial lobe (Ito et al., 2014). It is composed of the axons of gamma Kenyon cells (Ito et al., 2014).
A small bar-shaped subregion of the adult mushroom body that protrudes from the anterior dorsolateral edge of the calyx, lateral to the dorsal accessory calyx (Jenett et al., 2012). It contains the postsynaptic terminals of a subpopulation of around 14 alpha’/beta’ Kenyon cells (Yagi et al., 2016; Li et al., 2020), some of which only receive input in this region (Marin et al., 2020). It also contains some of the postsynaptic terminals of the gamma-s2 Kenyon cell (Marin et al., 2020; Li et al., 2020). The vast majority of presynapses in this region are from the temperature-sensitive antennal lobe VP3 vPN and VP2 adPN projection neurons (Marin et al., 2020; Li et al., 2020).
The lateral subregion of the adult mushroom body main calyx that contains two of the four neuroblast clones of Kenyon cells (Ito et al., 2014).

Glomerulus of the adult antennal lobe that receives input from olfactory neurons. There are approximately 51 of these per hemisphere (Bates et al., 2020).
Lateral subregion of the adult borboleta region (Munch et al., 2022). Its activity can stimulate yeast feeding in fed flies (Munch et al., 2022).
Ventrolateral subregion of the adult borboleta region (Munch et al., 2022).
Small region of the dorsal lateral part of the adult lateral accessory lobe, close to the bulb (Lin et al., 2013). The rubus is distinct from the round body (Wolff and Rubin, 2018).
Synaptic neuropil domain of the adult subesophageal zone that houses the axon terminals of sensory neurons (Miyazaki and Ito, 2010; Kendroud et al., 2018). These can be defined based on the projection patterns of neurons entering the brain via particular roots of the maxillary-labial, pharyngeal and antennal nerves (Kendroud et al., 2018).

Glomerulus of the ventro-posterior adult antennal lobe. These glomeruli receive input from non-olfactory sensory (thermosensory or hygrosensory) neurons (Marin et al., 2020).
Ventro-posterior glomerulus of the adult antennal lobe. It is located dorsomedial to glomerulus VP3, dorsoposterior to glomerulus V. Discernible with Golgi impregnation or CoCl2 backfills (Stocker et al. 1990), but not with nc82/bruchtpilot immunolabelling, leading to it not being represented in antennal lobe maps (Laissue et al., 1999, Couto et al., 2005) or having its position changed (Chou et al., 2010; Yu et al., 2010). According to Chou et al (2010) and Yu et al (2010) glomerulus VP1 is located medially to glomerulus VP2. The VP1 glomerulus corresponds to the target region of the Ir40-expressing olfactory sensory neurons, corresponding to the ‘column’ (Silbering et al., 2011). Tanaka et al (2012) identifies a new glomerulus, VP4, as another target region of Ir40a-expressing olfactory sensory neurons, which is innervated by different projection neurons to VP1. Grabe et al. (2015) merge glomeruli VP1 and VM6.

Discernible with Golgi impregnation or CoCl2 backfills (Stocker et al. 1990), but not with nc82/bruchtpilot immunolabelling, leading to it not being represented in antennal lobe maps (Laissue et al., 1999, Couto et al., 2005) or having its position changed (Chou et al., 2010; Yu et al., 2010). According to Chou et al (2010) glomerulus VP2 is located in between glomeruli VP1 and VP3. In Gallio et al (2011), glomerulus VP2 is described as corresponding to the medial region of the proximal antennal protocerebrum (PAP) which is innervated by hot-sensing neurons.

Discernible with Golgi impregnation or CoCl2 backfills (Stocker et al. 1990), but not with nc82/bruchtpilot immunolabelling, leading to it not being represented in antennal lobe maps (Laissue et al., 1999, Couto et al., 2005) or having its position changed relative to glomeruli VP1 and VP2 (Chou et al., 2010; Yu et al., 2010). According to Chou et al (2010) glomerulus VP3 is located laterally to glomerulus VP2. In Gallio et al (2011), glomerulus VP3 is described as corresponding to the lateral region of the proximal antennal protocerebrum (PAP) which is innervated by cold-sensing neurons.
Ventro-posterior glomerulus of the adult antennal lobe. It lies dorsoposterior to glomerulus VP3, ventral to DP1. Discernible with Golgi impregnation, but not with nc82/bruchtpilot immunolabelling, according to Tanaka et al. (2012) this glomerulus corresponds to part of the innervation region of IR40a ORNs, identified as the ‘arm’ by Silbering et al. (2011). Although VP1 and VP4 glomeruli are innervated by IR40a neurons, these correspond to different subsets and are therefore considered different glomeruli (Tanaka et al., 2012).
Small glomerulus of the adult posterior antennal lobe. It lies between VP2 and VP3 and is important in the response to humidity.
Central, non-glomerular region of the adult antennal lobe. It is distinguished from the antennal lobe glomeruli in that olfactory receptor neurons do not terminate here, though antennal lobe projection neurons and many local neurons run through this area. The density of synapses is lower than in the antennal lobe glomeruli.

Adult neuropil domain that receives the axonal projections of the Johnston organ neurons (JONs) (Ito et al., 2014). It is part of the saddle, which is found in a relatively dorsal part of the subesophageal zone (Ito et al., 2014). It develops from the anteriormost (tritocerebral) part of the larval central sensory column, which greatly increases in size as JON axons enter it via the antennal nerve during metamorphosis (Kendroud et al., 2018). Afferents of the JONs also invade the mandibular and maxillary neuromeres (Kendroud et al., 2018).

Antennal mechanosensory and motor center zone A is a synapse rich sub-region of the antennal mechanosensory and motor center (AMMC) formed from bifurcation of the Johnston’s organ bundle. (The other structure arising from this bifurcation is the main trunk of the AMMC (MT)). Zone A is rich in presynaptic sites of Johnston’s organ neurons. The cell bodies of zone A Johnston organ neurons are located mainly in the inner layer of Johnston’s organ, directly surrounding the antennal nerve (Kamikouchi et al., 2006). Presence of presynaptic sites of Johnston’s organ neurons determined by immunoreactivity to syntaxin and synaptobrevin::GFP localization (Kamikouchi et al., 2006).
Antennal mechanosensory and motor center zone B is a synapse rich sub-region of the antennal mechanosensory and motor center (AMMC) formed from the first bifurcation of the AMMC main trunk. It is rich in presynaptic sites of Johnston’s organ neurons (JONs). Presence of presynaptic sites determined by immunoreactivity to syntaxin and synaptobrevin::GFP localization (Kamikouchi et al., 2006).
Antennal mechanosensory and motor center zone C is a synapse rich sub-region of the antennal mechanosensory and motor center (AMMC) that arises from the most lateral half of the bifurcation at the end of the lateral core (LC) bundle (the other half of the bifurcation forms zone D). It is rich in the presynapses of Johnston’s organ neurons (JONs). It is composed of two branches (CM and CL), which merge at their posterior ends (Kamikouchi et al., 2006). Presence of presynaptic sites determined by immunoreactivity to syntaxin and synaptobrevin::GFP localization (Kamikouchi et al., 2006).
Antennal mechanosensory and motor center zone D is a synapse rich sub-region of the antennal mechanosensory and motor center (AMMC) that arises from the bifurcation that terminates the lateral core bundle. (The other half of the bifurcation forms zone C). It is rich in the presynapses of zone D Johnston’s organ neurons (zone D JONs). Presence of presynaptic sites determined by immunoreactivity to syntaxin and synaptobrevin::GFP localization (Kamikouchi et al., 2006).
Antennal mechanosensory and motor center zone E is a synapse-rich sub-region of the antennal mechanosensory and motor center (AMMC) that is continuous with the EA bundle. It is rich in presynaptic sites of Johnston’s organ neurons (JONs). Presence of presynaptic sites determined by immunoreactivity to syntaxin and synaptobrevin::GFP localization (Kamikouchi et al., 2006).
Sub-region of the antennal mechanosensory and motor center (AMMC) with a relatively ventral location within the AMMC (Hampel et al., 2020). It is innervated by neurons that elicit antennal grooming (Hampel et al., 2015; Hampel et al., 2020).
Region of the bulb that lies beneath the mushroom body pedunculus, closer to the somata of the ellipsoid body neurons than the superior and inferior bulb. It is formed by the antero-lateral and inferior extension of the lateral region of the superior bulb.
Region of the adult tritocerebrum that houses the axonal terminals of sensory neurons that enter the brain via the anterior root of the maxillary-labial nerve (Miyazaki and Ito, 2010; Kendroud et al., 2018) including gustatory receptor neurons of labellum sensilla (Miyazaki and Ito, 2010). It forms part of the anterior ventral sensory compartment (Kendroud et al., 2018). Three distinct subregions can be identified: a lateral anteriormost zone (AMS1), a lateralmost zone (AMS2) and a medial zone that reaches the midline (AMS3) (Miyazaki and Ito, 2010). Carbon-dioxide-sensitive neurons from the medial taste pegs of the labellum (identified in E409-GAL4 and NP107-GAL4) terminate in the AMS1 zone (Miyazaki and Ito, 2010).
Subregion of the anterior maxillary sensory center found dorsoanterior to anterior maxillary sensory center zone 2.

Subregion of the anterior maxillary sensory center found in the medial gnathal ganglion, reaching the midline.
Synaptic neuropil domain of the adult protocerebrum that receives extensive arborizations from visual projection neurons from the lobula and the medulla, projecting via the anterior optic tract. It protrudes from the anterior-most area of the ventro-lateral neuropils and is slightly detached from the ventro-lateral protocerebrum. This neuropil is absent from the larval brain, being formed during pupal development. Otsuna and Ito (2006) suggest that the optic tubercle may be divided into three regions according to the density of arborizations. The medial-most (optu1) and lateral-most (optu3) contain dense arborizations of the Lcn10 neurons, whilst the area between these regions (optu2) is essentially devoid of the lobula columnar neurons.

Anterior subregion of the superior lateral protocerebrum. Boundaries defined by Ito et al. (2014) (used to define this term) differ slightly from those defined for mslpr in Otsuna and Ito, 2006. There is no prominent natural boundary that clearly separates the posterior and anterior superior lateral protocerebrum. A frontal plane extrapolated from the boundary of the PVLP and PLP, which corresponds to the anterioposterior level of the great commissure, is used as a practical boundary.
Region of the superior medial protocerebrum anterior to the fan-shaped body. Because the fan-shaped body protrudes deeply into the SMP, its superior apex is used as a practical boundary landmark between anterior and posterior superior medial protocerebrum (Ito et al., 2014).

It runs through the space between the protocerebral bridge and the fan-shaped body, along the medial surface of the medial antennal lobe tract. The antler corresponds to part of the medial part of the pimpr of Otsuna and Ito (2006) and to the dorsal part of the caudalcentral protocerebrum (CCP) of Chiang et al., (2011) and to part of the posterior inferior protocerebrum (Ito et al., 2014).

Round synaptic neuropil of the central complex, adjacent to the ventralmost layer (1) of the fan-shaped body and dorsal to the noduli, on either side of the midline (Wolff and Rubin, 2018). The right asymmetrical body is, on average, 4x larger (by volume) than the left and some neurons have a bias towards the right hemisphere in their innervation patterns (Pascual et al., 2004; Jenett et al., 2012; Wolff and Rubin, 2018). In a small proportion (7.6%) of wild-type flies, this structure is symmetrical, with prominent (right side-like) innervation in both hemispheres (Pascual et al., 2004). This structure was identified by the expression of the neural protein fasciclin II (FasII) (Pascual et al., 2004). Wolff and Rubin (2018) claim this is a distinct neuropil to the fan-shaped body based on the restriction of neuronal arbors to one or the other.

A bilaterally paired synaptic neuropil domain located lateral to the ellipsoid body and anterior lateral to the fan-shaped body. It contains 80 microglomeruli characterized by their granular texture. It is formed primarily by the collateral arborizations of neuronal fibers that project to the ellipsoid body and by the terminals of the fibers projecting from the anterior optic tubercle and other neuropils. The bulb corresponds to the medial part of the mimpr of Otsuna and Ito, (2006) and to the lateral triangle of Chiang et al., (2011) (Ito et al., 2014).

A small, bilaterally paired, triangular synaptic neuropil domain that lies at the posterior end of the saddle. It is clearly demarcated by glial boundaries. The name ‘cantle’ was taken from the seat-back part of the horse-riding saddle. The cantle corresponds to the ventroposterior part of the ventromedial protocerebrum (VMP) of Chiang et al., (2011) and to the posterior periesophageal neuropils (Ito et al., 2014).

Central, most posterior, protrusion of layer 1 of the fan-shaped body at its ventral margin (Wolff et al., 2015). There is one of these teeth per fan-shaped body and it spans both hemispheres (Wolff et al., 2015).
Synaptic neuropil domain lying between the fan-shaped body, the protocerebral bridge and mushroom body pedunculus, including the area above and below the pedunculus (the space occupied by the pedunculus forms a deep tunnel-like recess on its inferior lateral side). Few neurons in the clamp penetrate the pedunculus, but some enter the glomerular posterior lateral protocerebrum and posterior ventrolateral protocerebrum (PLP, PVLP), forming a characteristic cylindrical architecture around the pedunculus. Some fibers spanning the superior surface project into the superior arch commissure.

A doughnut shaped synaptic neuropil domain of the central complex of the adult brain that lies just anterior to the fan-shaped body. Its hole (the ellipsoid body canal) points anteriorly and has an axon tract (the anterior bundle) running through it. It is divided into concentric layers and into 16 radial segments, 8 per hemisphere, numbered 1-8 from superior medial to inferior medial (Ito et al., 2014).
Small, most anterior subdivision of the ellipsoid body. It contains the arborizations of R5 ring neurons, and no other R-neurons (Omoto et al., 2017; Omoto et al., 2018). The ‘anterior ring’ of Hanesch et al. (1989) and ‘anterior disk’ of Renn et al. (1999) appear to refer to EBa, EBic and EBoc, collectively. The ‘anterior shell’ of Wolff et al. (2015) contains only EBa (Omoto et al., 2018).
Dorsalmost tile of the ellipsoid body, spanning both hemispheres (Wolff et al., 2015).
Dorsolateral tile of the ellipsoid body, between the dorsal and lateral tiles, there is one per hemisphere (Wolff et al., 2015).
Concentric subdivision of the ellipsoid body that lies anteriorly in the inner part of the ellipsoid body (Renn et al., 1999; Lin et al., 2013; Omoto et al., 2018). It contains the arborizations of R3a, R3d and R3m ring neurons (Omoto et al., 2018). The ‘anterior ring’ of Hanesch et al. (1989) and ‘anterior disk’ of Renn et al. (1999) appear to refer to EBa, EBic and EBoc, collectively. The ‘medial shell’ of Wolff et al. (2015) refers to EBic and EBoc (Omoto et al., 2018). Lin et al. (2013) included R2 neuron arborizations in this (EBA) domain, but Renn et al. (1999) and Omoto et al. (2018) assign them to the outer domain (EBoc).
Inner concentric subdivision of the posterior part of the ellipsoid body. It contains the arborization of R1 ring neurons, which mark the boundary between the inner and outer posterior domains (Omoto et al., 2018). The ‘posterior ring’ of Hanesch et al. (1989) and ‘posterior disk’ of Renn et al. (1999) appear to refer to EBop and EBip collectively. The ‘posterior shell’ of Wolff et al. (2015) also refers to EBop and EBip collectively (Omoto et al., 2018).
Lateralmost tile of the ellipsoid body, there is one per hemisphere (Wolff et al., 2015).
A concentric subdivision of the ellipsoid body resulting from the arborization patterns of the ring neurons (FBbt:00003649). Nomenclature for the layers is not consistent. Layers have been updated to correspond to Omoto et al. (2018), who claim to have a mostly complete map of R-neuron arborizations and provide mappings to previous terminology [FBC:CP].
A protuberance of the ellipsoid body on its dorsal anterior face (Wolff et al., 2015).

Outer concentric subdivision of the ellipsoid body. It contains the arborization of R2, R4d and R4m ring neurons (Renn et al., 1999; Young and Armstrong, 2010; Omoto et al., 2018). The ‘anterior ring’ of Hanesch et al. (1989) and ‘anterior disk’ of Renn et al. (1999) appear to refer to EBa, EBic and EBoc, collectively. The ‘medial shell’ of Wolff et al. (2015) refers to EBic and EBoc (Omoto et al., 2018). Lin et al. (2013) do not seem to include R2 neurons in the outer ring (EBO), but they are included by Renn et al. (1999) and by Omoto et al. (2018), who claim that EBO corresponds to EBoc.
Concentric subdivision of the ellipsoid body that lies posteriorly, distal to the canal (Omoto et al., 2018). It contains the arborization of R6 ring neurons (Omoto et al., 2018). The ‘posterior ring’ of Hanesch et al. (1989) and ‘posterior disk’ of Renn et al. (1999) appear to refer to EBop and EBip collectively. The ‘posterior shell’ of Wolff et al. (2015) also refers to EBop and EBip collectively (Omoto et al., 2018). This region was defined (as EBP) by Lin et al. (2013), but no R ring neurons known at the time arborized here.
A radial subdivision of the ellipsoid body arising from the arborization patterns of small field radial fibers. There are 16 of these per ellipsoid body, 8 per hemisphere numbered 1-8, from superior medial to inferior medial.

Any synaptic neuropil subdomain (FBbt:00040006) that is part of some ellipsoid body (FBbt:00003678).
A radial subdivision of the ellipsoid body (EB) posterior shell (outer and inner posterior domains). There are 8 of these per EB, with the dorsal and ventral tiles spanning both hemispheres (Wolff et al., 2018). Each tile is connected to two protocerebral bridge (PB) glomeruli by each EB tile cell type with glomerular arbors in the PB (Wolff et al., 2015).
Ventralmost tile of the ellipsoid body, spanning both hemispheres (Wolff et al., 2015).
Ventrolateral tile of the ellipsoid body, between the ventral and lateral tiles, there is one per hemisphere (Wolff et al., 2015).
Paired synaptic neuropil domain of the larval deutocerebrum, located ventral to the mushroom body, that is the major target of innervation for axons carried by the antennal nerve. It is also connected to the antero-basal tract (ABT). Its posterior boundary contacts the lateral accessory lobe, ventromedial cerebrum, ventrolateral protocerebrum and periesophageal neuropils. It is the larval counterpart of the adult antennal lobe, and consists of around 22 glomeruli. Note - description of relative location of brain structures in this definition is based on Younossi-Hartenstein et al., 2003 description of the first instar larval brain and Pereanu et al., 2010 third instar larval brain.
Antennal lobe glomerulus of the larva. There are 21 glomeruli, each innervated by a single type of olfactory receptor neuron (Masuda-Nakagawa et al., 2009).
