SIMPAL

ID: FBbt_00049654

Neuron with its soma close to the dorsal midline of the brain, lateral projections into the ipsilateral superior medial and intermediate protocerebra, and ventral projections to the subesophageal zone and antennal lobe (AL) (Coates et al., 2020). It innervates approximately 23 glomeruli in the ipsilateral AL before crossing the antennal commissure into the contralateral AL (Coates et al., 2020). In both antennal lobes, these neurons have a substantial number of output synapses onto the CSD neuron, particularly in the DP1m, DP1l and DC1 glomeruli (Coates et al., 2020). They also receive significant input from the dense ABAF local neurons, most strongly in the same glomeruli in which the SIMPAL neurons provide the greatest synaptic input to the CSD (Coates et al., 2020). There are two of these neurons per hemisphere (Coates et al., 2020).
