Olfactory bulb, mouse

A coronal section through the main olfactory bulb of an adult male mouse (strain: C57BL/6j). Image taken with a confocal microscope visualizing all cell nuclei with stain TOTO-3.

False color applied with photoshop to indicate the three main anatomical layers:
Blue - Glomerular layer containing periglomerular (juxtaglomerular cell bodies)
Red - External Plexiform layer and Mitral cell layer containing cell bodies of mitral and tufted cells (and granule cells resident in mitral cell layer)
Green - Internal plexiform and granule cell layer containing cell bodies of immature migrating neuroblasts, and mature granule cells.
