adult hygrosensory neuron Ir40a VP1d [FBbt_00047226]
Adult hygrosensory neuron that expresses the humidity-sensing Ionotropic receptor (Ir) 40a, and the co-receptors Ir93a and Ir25a and innervates the antennal lobe glomerulus VP1d (Enjin et al, 2016; Knecht et al., 2016; Marin et al., 2020). It receives sensory input in the blunt-tipped sensilla of chamber II of the sacculus and its projections remain strictly ipsilateral (Silbering et al., 2011; Marin et al., 2020). It is activated by dry air (to a lesser extent than the VP4 Ir40a neurons) (Knecht et al., 2016) and by large decreases in temperature (Enjin et al., 2016), which may collectively correspond to detection of evaporative cooling (Marin et al., 2020). There are around 7-9 of these cells per hemisphere (Marin et al., 2020).
