General Information
Term ventrolateral protocerebrum projection neuron 1 ID (Ontology) FBbt:00111295 (Fly Anatomy)
Definition Projection neuron whose cell body is located in the cell body rind of lateral neuropils. It arborizes in the wedge and projects dorsally to the region surrounding the mushroom body peduncle (superior intermediate protocerebrum and clamp). This neuron is not found in females. It responds to both pulse and sine song at 80dB.[ FlyBase:FBrf0229653 ]
Also Known As "vPN1"
Comment Image registration analysis supports an overlap between the dendrites of vPN1 neurons and axons terminals of AMMC-B1 neurons in the wedge; as well as between the axon terminals of vPN1 neurons and dendrites of adult fruitless pMP-e (male) neuron (pC1) in the superior intermediate protocerebrum. Auditory responses were assayed using in vivo calcium imaging (Zhou et al., 2015).
