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 VP4 bilaterally (Enjin et al, 2016; Knecht et al., 2016; Marin et al., 2020). There are two subtypes that transduce signals from the basiconic sensilla of chamber I or the blunt-tipped sensilla of chamber II (pore-less sensilla) of the sacculus (Enjin et al., 2016; Marin et al., 2020). Its activity is increased by dry air and decreased by humid air (Knecht et al., 2016; Enjin et al., 2016). It develops from an Nba precursor (Benton et al., 2025). There are around 15 of these cells on each side (Benton et al., 2025).
