General Information
Term aristal sensory neuron VP2 ID (Ontology) FBbt:00007575 (Fly Anatomy)
Definition Adult unilateral thermosensory neuron of the aristal sensillum with an axon that innervates antennal lobe glomerulus VP2 (Stocker et al., 1990; Benton et al., 2025). It has small, finger-like sensory endings (Budelli et al., 2019) and expresses the warmth-sensor Gr28b.d (Ni et al., 2013). It is transiently activated by temperature increases and transiently inhibited by temperature decreases (Budelli et al., 2019). In addition, it has increased steady state spiking at higher temperatures (Budelli et al., 2019). There are around 3-4 of these cells per hemisphere (Marin et al., 2020).[ FlyBase:FBrf0051437 FlyBase:FBrf0213085 FlyBase:FBrf0222493 FlyBase:FBrf0241574 FlyBase:FBrf0246456 FlyBase:FBrf0262710 ]
