larval A27j neuron [FBbt_00111666]
Neuron of the larval abdominal neuromere that is part of lineage 27. Its primary neurite extends from the dorsolateral edge of the ventral nerve cord medially, and then follows the midline ventrally. It receives substantial input from the ipsilateral A02a, A27e, contralateral A31k neuron, dorsal multidendritic neuron dda1, ddaD (Schneider-Mizell et al., 2016). It has strong outputs to the larval A27e (axo-axonic connection) and ipsilateral A1-7 dorsal motor neuron (Schneider-Mizell et al., 2016). It is a GABAergic neuron (Schneider-Mizell et al., 2016). It may be involved in avoidance behavior (Vogelstein et al., 2014). 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 where available; ipsi- and contralateral connections separated by comma): from A02a (15/10), A27e (15), A31k (10/8), dda1 (21), ddaD (21), ddaE (7). The number of output synapses was the following: to A27e (18), A1-7 dorsal motor neuron (12/25) (Schneider-Mizell et al., 2016). This is one of three types of neuron that express R25B07, it is not clear which is/are responsible for turning and crawling behavior (Vogelstein et al., 2014).
