Figure 1 Humidity sensing in Drosophila. The sacculus resides in an invaginated region of the Drosophila antenna similar to other insect species. Some sensilla in the sacculus, unlike olfactory sensilla, have no pores and typically contain three neurons. Enjin et al. [4] have identified two of the three neurons, with one exclusively responding to cold temperature and projecting to the Column glomerulus in the antennal lobe. The other neuron responds to dry air and projects its axon to the Arm glomerulus. Ir40a is required for neuronal responses to dry air but not cold temperature. The moisture-sensitive neuron has yet to be identified. Current Biology 2016 26, R408-R410DOI: (10.1016/j.cub.2016.04.040) Copyright © 2016 Elsevier Ltd Terms and Conditions
