Basal Ganglia Malformations

The basal ganglia are composed of several interconnected nuclei, including the caudate nucleus, putamen, and globus pallidus. These structures work together to help regulate voluntary movements by sending signals to different parts of the brain.

The claustrum is a thin layer of neurons located within the brain, adjacent to the insular cortex. Despite its small size, the claustrum is believed to be involved in various cognitive functions, such as consciousness and attention. It acts as a communication hub, relaying information between different brain regions. Malformation refers to an abnormality or irregularity in the structure or development of an organ or body part.  Malformations can occur during fetal development or later in life due to genetic factors, environmental influences, or a combination of both. These abnormalities can range from minor variations to more severe defects that may impact function.
