olfactory bulb layer olfactory bulb granule cell layer DMBA:15909 granule layer of main olfactory bulb The granule cell layer contains multiple small round neurons that lack axons. Long dendritic processes of the neurons reach the more superficial layers and inhibit mitral cells and tufted cells. Small distal processes make contacts with the exiting mitral cell axons.
