(2021) - FBrf0250923 unsure whether this is ac1C or ac1D. Olfactory receptor neuron Ir75d with its sensory dendrite in an antennal coeloconic sensillum ac1 (Silbering et al., 2011). It responds strongly to changes in humidity (Yao et al., 2005). There are around 15 of these cells per hemisphere (Grabe et al., 2016).
