General Information
Term larval Basin neuron ID (Ontology) FBbt:00047194 (Fly Anatomy)
Definition Segmentally-repeated interneuron of the larval ventral nerve cord that is mid-late born in the primary NB3-5 lineage (Ohyama et al., 2015; Wang et al., 2022). The four Basin neurons in each hemineuromere are born from consecutive ganglion mother cells, in the order Basin-2, -1, -3, -4 (Wang et al., 2022). Its soma is located in the lateral cell body rind region and its cell body fiber follows an intersegmental nerve root into the neuropil (Ohyama et al., 2015). Its dendrites span a ventrolateral domain of the ventral nerve cord and overlap with the axon terminals of the mechanosensory chordotonal neurons, from which it receives input (Ohyama et al., 2015).[ FlyBase:FBrf0228257 FlyBase:FBrf0233796 FlyBase:FBrf0254149 ]
