The piriform (pyriform) cortex is the ancient cortex of the rostral part of the piriform lobe. The name has traditionally been used as a general term for the rostral olfactory nucleus, the primary olfactory (or piriform) cortex, and the entorhinal region, which forms a more or less pear-shaped structure, at least in macrosmatics like the rat.   The entorhinal cortex occupies most of the parahippocampal gyrus and is located on the ventromedial surface of the brain.

The following layers can be distinguished in the entorhinal cortex: molecular, stellate, pyramidal, large cell, small cell, and multiform. The data presented in the article can serve as a fundamental basis for further study of the parts of the rat brain in normal and pathological conditions with further extrapolation of the obtained data to humans.
