Definition Principal neuron located in the olfactory Principal neuron located in the olfactory bulb in the mammalian central nervous system. The cell bodies are arranged in a thin layer between the granule cell layer and the external plexiform layer. Each mitral cell is usually characterized in the mammal by a single primary dendrite that traverses the external plexiform layer and terminates within an olfactory glomerulus in a tuft of branches which receives input from the axons of olfactory receptor neurons. Axons of the mitral cells project to a number of areas in the brain, including the piriform cortex, entorhinal cortex, olfactory tubercle, and amygdala. cortex, olfactory tubercle, and amygdala.

DendriteThickness Rat: Apical trunk: 2-6; apical tuft: 1-2 um at origin; basal: 2-3 um at origin, narrowing through branching to less than 1 um.  +
EditorialNote I changed protocadherin-2 to Protocadherin gamma-C3, as that seems to be the preferred name in NCBI and the Protein Ontology. Changed TBX-21 to T-box protein 21, to distinguish it from the gene. Please let me know if these changes aren't appropriate. know if these changes aren't appropriate.
