General Information
Term non-aristal sensory neuron VP3 ID (Ontology) FBbt:00049720 (Fly Anatomy)
Definition Thermosensory neuron that innervates the ipsilateral antennal lobe glomerulus VP3, but does not receive sensory input in the arista (Liu et al., 2015; Marin et al., 2020; Alpert et al., 2020). There are one or two of these cells per hemisphere, with their cell bodies at the edge of the antennal nerve (Alpert et al., 2020). It has simpler arbors in the antennal lobe than the VP3 neurons of the arista (Marin et al., 2020). It provides most of the input to the slow-cool VP3 vPN (Liu et al., 2015; Marin et al., 2020).[ FlyBase:FBrf0227881 FlyBase:FBrf0246007 FlyBase:FBrf0246456 ]
Also Known As"ACc" ; "anterior cold cell" ; "VP3RNb"
CommentACc from Alpert et al. (2020) judged to be the same as VP3RNb from Marin et al. (2020) based on lack of aristal dendrite, arborization in VP3 (cold glomerulus) and connections to VP3 vPN (slow-cool PN).
