The drawing to the left is a sketch of a cross-section from a rat's brain. The section was sliced using a freezing microtome, and then a nissl stain was used to define certain characteristic areas in the cross-section. The coronal slice of the rat brain is about 50 microns thick and is found on Plate 18 of the stereotaxic atlas. The terminology of the various parts of the brain are listed below, followed by their abbreviations underneath.
