The area gigantopyramidalis has been circumscribed on frontal serial sections of brains of mouflons (Ovis ammon musimon) and domestic sheep (Ovis ammon f. aries). A brief description of the topography and lamination of the area 4 is given.

By means of intraspecific-allometric methods this area has shown a decrease in volume by 29.9% in domestic sheep compared with wild sheep.

In view of the close relationship between size and function of a structure the reduction rates of the area gigantopyramidalis, the cerebellum and the basal ganglia are discussed as due to the special environmental changes caused by domestication.
