| Definition |
Larval period-positive median segmental interneuron (PMSI) (Kohsaka et al., 2019) that is late-born in the NB2-1 Notch OFF 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 additionally turns back ventrally, close to the midline, at the end of the loop (Schneider-Mizell et al., 2016; Kohsaka et al., 2019). It receives input from the ipsilateral dorsal bipolar neuron dbp and outputs to the ipsilateral A27j neuron and A02b neurons of both hemineuromeres (Schneider-Mizell et al., 2016).[ FlyBase:FBrf0231328 FlyBase:FBrf0242656 FlyBase:FBrf0249021 ] |

| Comment |
These neurons were identified in a EM reconstruction of a volume that includes the posterior half of abdominal segment 2 and abdominal segment 3, of a 12-24h old first instar larva. The number of connections was estimated from the publication figures. The number of input synapses was the following (number in brackets left/right; ipsi- and contralateral connections separated by comma): from dbp (35/35), A02b (5/10). The number of output synapses was the following: to A27j (15/10), A02b (8, 18/20, 18) (Schneider-Mizell et al., 2016). Looper-1 synonym from catmaid. |
