The substantia nigra of the rat: A golgi study

Three variants of the Golgi method were employed to examine the cell types, their dendritic fields and organization and azonal trajectories within the substantia nigra of albino and hooded rats. In both sagittal and coronal sections, large, medium and small neurons were classified on the basis of soma size, extent of dendritic fields and dendritic caliber. In general nigral cells have three to five primary dendrites that branch relatively infrequently. Some dendrites of all cell types have thinly scattered spines or varicosities.
