ORN_DC4 [FBbt_00111210]

Adult olfactory receptor neuron Ir64a that innervates the antennal lobe DC4 glomerulus, bilaterally (Ai et al., 2010; Silbering et al., 2011). Its dendrite transduces signals from a grooved sensillum of the ventral compartment of chamber III of sacculus (Shanbhag et al., 1995). It responds to acid (H+ ions) and carbon dioxide (Ai et al., 2010). There are around 10 of these cells on each side (Benton et al., 2025).
