adult medulla-tubercle neuron of dorsal rim area [FBbt_00052133]

Adult medulla-tubercle (MeTu) neuron that receives input from R7 (and not R8) photoreceptors of the dorsal rim area (DRA) in the proximal part of medulla layer M6 (Kind et al, 2021). Its arbors span several columns, and may include columns outside of the DRA, though its non-DRA arbors are just proximal to M6, avoiding photoreceptor terminals (Kind et al., 2021). It has presynaptic sites in the small unit of the anterior optic tubercle, in a region distinct from the terminals of non-DRA MeTu neurons (Kind et al, 2021).

larval light avoidance neuron [FBbt_00052271]

Larval neuron with its soma in the dorsolateral supraesophageal ganglion, dendrites in the superior protocerebrum, where it receives input from Pdf neurons, and a smaller contralateral branch (Gong et al., 2010). Its activity results in light avoidance behavior (Gong et al., 2010). There are two of these cells per hemisphere (Gong et al., 2010). Only referred to as ‘NP394-Gal4 neuron’ in Gong et al. (2010). Synapsing with Pdf neurons shown by GRASP and functional experiments (Gong et al., 2010).

lobula plate tangential neuron FD1 [FBbt_00052268]

Lobula plate tangential neuron that innervates the lateral region of ipsilateral lobula plate (LOP) layers 1 and 2, with sparse terminals in layer 3, as well as the ipsilateral posterior lateral protocerebrum (PLP) and the contralateral inferior posterior slope (IPS) (Wei et al., 2020). Its LOP and PLP terminals are postsynaptic and its IPS terminals are presynaptic (Wei et al., 2020). It also has a small branch extending to the lobula (Wei et al., 2020). Its soma is located on the posterior surface of the lateral central brain (Wei et al., 2020). It is cholinergic (Wei et al., 2020).

lobula plate tangential neuron FD3 [FBbt_00052269]

Lobula plate tangential neuron that innervates the medial region of ipsilateral lobula plate (LOP) layer 2, as well as the ipsilateral posterior lateral protocerebrum (PLP) and the contralateral inferior posterior slope (IPS) (Wei et al., 2020). Its LOP and PLP terminals are postsynaptic and its IPS terminals are presynaptic (Wei et al., 2020). Its soma is located on the posterior surface of the lateral central brain (Wei et al., 2020). It is cholinergic (Wei et al., 2020).

lobula plate tangential neuron H2 [FBbt_00052267]

Lobula plate tangential neuron that innervates most of the ipsilateral lobula plate (LOP) layer 2 and the contralateral inferior posterior slope (IPS) (Wei et al., 2020). Its LOP terminals are mixed pre- and post-synaptic and its IPS terminals are presynaptic (Wei et al., 2020). Its soma is located on the posterior surface of the lateral central brain (Wei et al., 2020). It is cholinergic (Wei et al., 2020).

medulla tangential visual projection neuron 1 [FBbt_00052141]

Medulla tangential projection neuron that has processes in medulla layer M7 and branches reaching up to M5-M6 (Kind et al., 2021). It receives input from several R7 photoreceptor cells (Kind et al., 2021). It projects an axon to the posterior lateral protocerebrum (Kind et al., 2021).

medulla-lobula visual projection neuron 1 [FBbt_00052138]

Visual projection neuron with its cell body near the anterior proximal medulla and an axonal projection following that of the medulla-lobula neuron 1 (Kind et al., 2021). It has wide-field dendritic arborization in the medulla, spanning tens of columns, ramifying at the border of layers M7/M8, then sending vertical projections to M3 and then to M1, and expanding laterally in each of these layers (Kind et al., 2021). Its main synaptic input from photoreceptors is from R8 cells of pale ommatidia (Kind et al., 2021). It projects to the ipsilateral posterior lateral protocerebrum, innervating a region just behind the optic glomeruli (Kind et al., 2021). There are approximately 65 of these cells per optic lobe (Kind et al., 2021).
