Caudate nucleus and putamen together form which brain structure?

The caudate nucleus and putamen are critical components of the basal ganglia, and when they are referred to together, they form a structure known as the striatum. The striatum plays a vital role in the regulation of movement as well as various cognitive processes and rewards. It functions as a primary input center for the basal ganglia circuitry, facilitating the integration and processing of information.

The caudate nucleus is involved in motor control and also plays a role in learning and memory, whereas the putamen primarily influences movement and behavior. Their collaboration within the striatum allows for complex functions related to motor planning, action selection, and the reinforcement of behaviors.

Understanding this concept is crucial for grasping the overall functioning of the basal ganglia and its involvement in both motor activity and neuropsychiatric disorders.
