These regions project to the thalamus by the direct path through Forel's fields surrounding the zona incerta, and by the indirect path through ansa lenticularis around the subthalamic nucleus.
These regions project to the thalamus by the direct path through Forel's fields surrounding the zona incerta, and by the indirect path through ansa lenticularis around the subthalamic nucleus. Their cells are divided into cholinergic matrisomes and peptide-rich striasomes, and lesions in them can cause the sinusoidal movement known as athetosis. Lying medial to the claustrum, they contain the nuclei accumbens that connect two of their components, and receive fibers from the substantia nigra. Disorders like St. Vitus dance and dyskinesia are associated with lesions in their components, which include globus pallidus, caudate, and putamen. FTP name these areas of the brain surrounding the internal capsule involved in motor programming.
