anterior olfactory nucleus
The neurons clustered along the olfactory tract. Some axons from the mitral cells in the olfactory bulb synapse on anterior olfactory neurons, and anterior olfactory neurons contribute axons to the olfactory tract. The anterior olfactory nucleus, which is distinct in most mammals, is sparse in primates.
