General Information

Term

larval GABAergic dorsolateral neuron

ID (Ontology)

FBbt:00111674 (Fly Anatomy)

Definition

Larval neuron of the ventral nerve cord that is part of lineage 27, there is one of these per hemisegment in A1-7 (Fushiki et al., 2016). It enters the neuropil laterally, its axon terminals are found in a lateral area of the neuropil under the DL fascicle and its dendrites arborize in the motor domain (Fushiki et al., 2016). It is a GABAergic neuron required for the normal propagation of the peristaltic waves during locomotion (Fushiki et al., 2016). It is not directly connected to motor neurons, but it receives input from (in the next posterior segment) and outputs onto (in the same segment) several premotor neurons, having particularly strong output to the excitatory A27h neuron (Fushiki et al., 2016). It also receives input from ventral multidendritic neurons (vdaA and/or vdaC) in the same segment (Fushiki et al., 2016).[ FlyBase:FBrf0231611 ]

Also Known As

"GDL neuron" ; "larval A27j2 neuron"

Comment

These neurons were identified in two EM reconstructions: one of the full CNS of a 6h old first instar larva, and another of abdominal segment 3 of a 12-24h old first instar larva. The number of identified input synapses was the following (number in brackets): from A27h (5), from vdaA (5), from vdaC (9), from A27k (7), A02j (7 (first posterior segment) and 6 (second posterior segment)) and from A03a4 (6). The number of identified output synapses was the following (number in brackets left/right): to A27h (32/41), to A31d (13/12), to A05k (7/7), to A27k (2/9), to SA1 (A06l) (6/4), to A31x (15/8), to A27a (17/11), to A08e3 (12/12), to A02d (7/8), to A27p (1/5), to A27e (5/5), to A03ax (5/5), to A05x (4/3), to A01b2 (1/7), A09x (5/5). Neurotransmitter identified by antibody staining (Fushiki et al., 2016).
