Globus Pallidus

The globus pallidus (Latin for “pale globe”) is a structure located deep within the brain and is part of the basal ganglia, which regulate movement and coordination. It is composed of two components: the pallidus interna and pallidus externa. The pallidus interna is involved in the regulation of movement and coordination by sending signals to the ventral thalamus, which in turn sends signals to premotor regions in the brain. The pallidus externa plays a role in cognitive functions, such as attention and decision-making. Damage to the globus pallidus can lead to serious neurological problems, including movement disorders, such as Huntington’s disease and Parkinson’s disease, and cognitive issues, such as dementia. The globus pallidus is a critical structure in understanding how the brain regulates movement and cognition.
