Odor receptors send output directly, left to left and right to right, to 2-mm-diameter brain region {olfactory bulb}| above and behind nose. Olfactory receptors send axons to mitral cells. Mitral-cell axons go to anterior-olfactory-nucleus and prepyriform-cortex superficial and deep pyramidal neurons. Pyramidal neurons send recurrent collateral axons to superficial pyramidal neurons and stellate cells. Pyramidal neurons have post-synaptic apical dendrites that receive from other pyramidal neurons. Tufted cells are local. Olfactory nerves, mitral cells, and tufted cells meet in olfactory-bulb glomeruli. Olfactory bulb preserves odor-receptor spatial relations. Olfactory bulb has fewer neurons than number of odor receptors.
