Golgi morphology of the neurons in frontal sections of human interthalamic adhesion.

The Golgi morphology of the neurons in the human interthalamic adhesion (IA, which is not present in every human brain) is very variable. Four types of Golgi-impregnated neurons were found in the adult human IA: (1) fusiform neurons (most characteristic of the human IA); (2) neurons with an oval perikaryon; (3) triangular neurons (rarely found), and (4) multipolar neurons (polygonal perikaryon and at least 4 primary dendrites). Fusiform neurons, as well as triangular and multipolar ones, belong to the isodendritic type, but the neurons with oval perikarya do not.
