A cytoarchitectonic volumetric comparison of the area gigantopyramidalis in wild and domestic sheep.

Anatomy and Embryology

Abstract

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.

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
