ORN_DP1l [FBbt_00110013]

Adult olfactory receptor neuron that expresses the Ionotropic receptor (Ir) 75a and the co-receptor Ir8a (Benton et al., 2025). It innervates antennal glomerulus DP1l bilaterally (Silbering et al., 2011; Kaur et al., 2019). Its dendrite transduces signals from antennal coeloconic sensillum ac2 (Benton et al., 2009). It responds to carboxylic acids (Benton et al., 2025). It develops from an Nab precursor (Benton et al., 2025). There are around 12 of these cells on each side (Benton et al., 2025).

Adult olfactory receptor neuron that expresses the Ionotropic receptor (Ir) 75a and the co-receptor Ir8a (Benton et al., 2025). It innervates antennal glomerulus DP1l bilaterally (Silbering et al., 2011; Kaur et al., 2019). Its dendrite transduces signals from antennal coeloconic sensillum ac2 (Benton et al., 2009). It responds to carboxylic acids (Benton et al., 2025). It develops from an Nab precursor (Benton et al., 2025). There are around 12 of these cells on each side (Benton et al., 2025).

This neuron was indirectly shown to be olfactory by electrophysiological recordings of a single coeloconic sensillum (Benton et al., 2009).
