General Information
Term larval A02h neuron ID (Ontology) FBbt:00048696 (Fly Anatomy)
Definition Larval period-positive median segmental interneuron (PMSI) (Kohsaka et al., 2019) that is late-born in the NB2-1 Notch ON primary hemilineage (Mark et al., 2021). Like other PMSIs it has a ventral soma and it extends dorsally, close to the midline, then forms a loop in the dorsal neuropil (Kohsaka et al., 2019). This neuron has a bifurcation in the lateral part of the loop that produces a relatively long ventrally-extending branch, and the loop is relatively small, as the neurites do not travel far back medially (Kohsaka et al., 2019). It receives direct input from sensory neurons (Kohsaka et al., 2019) and it is a premotor neuron (Zarin et al., 2019).[ FlyBase:FBrf0233076 FlyBase:FBrf0242656 FlyBase:FBrf0244727 FlyBase:FBrf0249021 ]
