| Term |
aristal sensory neuron VP3 |
ID (Ontology) |
FBbt:00007576 (Fly Anatomy) |
| Definition |
Adult unilateral thermosensory neuron with its sensory dendrite in an aristal sensillum and an axonal projection to antennal lobe glomerulus VP3 (Stocker et al., 1990; Alpert et al., 2020; Benton et al., 2025). It has large, elaborate sensory endings (Budelli et al., 2019). It is transiently activated by temperature decreases and transiently inhibited by temperature increases (Budelli et al., 2019). It expresses the cooling-specific Ir21a and the co-receptors Ir25a and Ir93a, with all three being required for sensitivity to cooling (Budelli et al., 2019). There are around 3-4 of these cells per hemisphere (Marin et al., 2020).[ FlyBase:FBrf0051437 FlyBase:FBrf0213085 FlyBase:FBrf0241574 FlyBase:FBrf0246007 FlyBase:FBrf0246456 FlyBase:FBrf0262710 ] |
