larval serotonergic A4 neuron 1

ID: FBbt_00047337

Larval serotonergic A4 neuron with its cell body located more medially. The axon bifurcates into two thick branches as it enters dorsally into the contralateral neuropil. These two primary branches initially diverge in opposite directions and grow along the medial two-thirds of the neuropil, forming a circular pattern, with the branches meeting at the dorsal end of the neuropil. These neurons also extend an ipsilateral neurite, that seems to fasciculate with the respective ipsilateral neurite of the A4-2 neuron, projecting anteriorly to form the majority of its branches in the next anterior segment (A3).
