General Information
Term oviposition inhibitory neuron ID (Ontology) FBbt:00049928 (Fly Anatomy)
Definition GABAergic neuron of the adult female that synapses onto and inhibits oviposition descending neurons, and reduces oviposition (Wang et al., 2020). It has reciprocal connections to the oviposition excitatory neuron and to pC1 neurons, and it also receives sensory information about the laying substrate (Wang et al., 2020). There is one of these cells per hemisphere (Wang et al., 2020). Its cell body is located in the lateral subesophageal zone, it projects medially, then dorsally, and densely innervates the ipsilateral superior medial protocerebrum (Wang et al., 2020). A branch crosses the midline and sparsely innervates the contralateral superior medial protocerebrum (Wang et al., 2020).[ FlyBase:FBrf0245074 ]
