Bilateral larval neuron with postsynaptic terminals in the mushroom body lateral appendix in the first instar; this changes to the lower two regions of the vertical lobe (V1 and V2) in the third instar. Its presynaptic sites are found in the centroposterior medial compartment (posterior inferior protocerebrum) and centroposterior intermediate compartment (clamp). It outputs onto FBN-9, FBN-16 and FAN-6 (Eschbach et al., 2020). It develops from neuroblast DAMd1 (Saumweber et al., 2018).
Larval neuron with postsynaptic terminals in all three regions of the ipsilateral vertical lobe (V1, V2 and V3) in the third instar, but only V3 in the first instar (Saumweber et al., 2018). Its presynaptic sites are found in the ipsilateral and contralateral centroposterior medial compartment (posterior inferior protocerebrum) and centroposterior intermediate compartment (clamp) (Saumweber et al., 2018). It is glutamatergic (Eichler et al., 2017). Its activity promotes turning behavior (Eschbach et al., 2021). It develops from the DAMd1 neuroblast (Saumweber et al., 2018) and becomes an adult MBON03 during metamorphosis (Truman et al., 2023).
Bilateral larval neuron that has presynapses in the centroposterior medial compartment (posterior inferior protocerebrum) and dorsoanterior compartment (anterior superior medial protocerebrum) and postsynapses in the dorsal part of the medial region (upper toe) of the mushroom body medial lobe (Saumweber et al., 2018). It is glutamatergic (Eichler et al., 2017). It outputs onto FAN-7 (Eschbach et al., 2020). Its activity promotes turning behavior (Eschbach et al., 2021). It develops from neuroblast DAMd1 (Saumweber et al., 2018) and becomes an MBON04 during metamorphosis (Truman et al., 2023).
Larval neuron that has presynapses in the centroposterior lateral compartment (clamp), dorsoposterior compartment (posterior superior medial protocerebrum) and dorsoanterior compartment (anterior superior medial protocerebrum). It has postsynapses in the medialmost part of the medial lobe (intermediate toe) of the mushroom body in both hemispheres (Saumweber et al., 2018). It is glutamatergic (Eichler et al., 2017). It outputs onto FBN-1 (Eschbach et al., 2020). It develops from neuroblast DAMd1 (Saumweber et al., 2018) and becomes an MBON02 during metamorphosis (Truman et al., 2023).
Bilateral larval neuron that has presynapses in the dorsoanterior compartment (anterior superior medial protocerebrum) and postsynapses in the ventral part of the medial region (lower toe) of the mushroom body medial lobe (Saumweber et al., 2018). It is glutamatergic (Eichler et al., 2017). It outputs onto FAN-1, FAN-9 and FAN-11 (Eschbach et al., 2020). Its activity promotes turning behavior (Eschbach et al., 2021). It develops from neuroblast DAMd1 (Saumweber et al., 2018) and becomes an MBON01 during metamorphosis (Truman et al., 2023).
