General Information

Term

neuron of aristal sensillum

ID (Ontology)

FBbt:00004186 (Fly Anatomy)

Definition

Sensory neuron with its sensory dendrite in an aristal sensillum. Each sensillum contains two of these neurons, which detect changes in temperature and project via the aristal nerve, then the antennal nerve, to the antennal lobe (Stocker et al., 1983; Budelli et al., 2019).[ FlyBase:FBrf0039019 FlyBase:FBrf0051437 FlyBase:FBrf0137012 FlyBase:FBrf0241574 ]

Comment

Innervation pattern of arista sensory neurons determined by cobalt back-fill (Stocker et al., 1983, Stocker et al., 1990). Foelix et al. (1989), suggest that the morphology of the highly lamellated neurons is consistent with a thermosensory function based on the similarity of this morphology to that of thermosensory neurons in the antennae of other insects.
