[英文释义] Neurons in the olfactory epithelium with proteins (RECEPTORS,ODORANT) that bind,and thus detect,odorants. Olfactory receptor neurons are bipolar. They send to the surface of the epithelium apical dendrites with non-motile cilia from which project odorant receptor molecules. Their unmyelinated axons synapse in the olfactory bulb of the brain. Unlike other neurons,they can be generated from precursor cells in adults.
