The basal ganglia consist of five closely cooperating nuclei: the caudate nucleus, substantia nigra, subthalamic nuclei, putamen and globus pallidus. These five nuclei of the basal ganglia regulate motivation and motor movements. The putamen and globus pallidus together form the lentiform nucleus.

• Putamen (brown): Form a cube and press it into a trapezoidal shape.
• Globus Pallidus (orange): Model a triangle and place it directly under the putamen, forming the lentiform nucleus. Push the lentiform nucleus into the internal capsule on both lateral sides so that only the putamen is visible.
