The neurons of the human magnocellular septal nuclei: a Golgi study.

ABSTRACT

The morphology of neurons in the magnocellular septal nuclei (medial septal and diagonal band nucleus) were studied in frontal sections of 15 human brains by means of the Golgi method. We classified neurons in the diagonal band nucleus according to their size and morphology into four types type I--multipolar neurons, type II--fusiform neurons, type III--triangular neurons and type IV--fusiform multipolar neurons. The neurons of the medial septal nucleus we classified into two types type I--multipolar neurons and type II--fusiform neurons. Our results indicated greater morphological variability of neurons in the human diagonal band nucleus than in the medial septal nucleus.
