The basal ganglia are an area of the brain where gender differences in brain physiology is evident. The basal ganglia are a group of nuclei in the brain that is responsible for a variety of functions, some of which include movement. The globus pallidus and putamen are two nuclei of the basal ganglia which are both involved in motor skills. The globes pallid-us is involved with the voluntary motor movement, while the putamen is involved with motor learning. Even after controlling for the naturally larger volume of the male brain, it was found that males have a larger volume of both the globus pallidus and putamen.
