Posterior limb of internal capsule

Overview
The posterior limb of internal capsule (or occipital part) is the portion of the internal capsule posterior to the genu.

Anterior
The anterior two-thirds of the occipital part of the internal capsule contains the cerebrospinal fibers, which arise in the motor area of the cerebral cortex and, passing downward through the middle three-fifths of the base of the cerebral peduncle, are continued into the pyramids of the medulla oblongata.

Posterior
The posterior third of the occipital part contains:
 * (1) sensory fibers, largely derived from the thalamus, though some may be continued upward from the medial lemniscus;
 * (2) the fibers of optic radiation, from the lower visual centers to the cortex of the occipital lobe;
 * (3) acoustic fibers, from the lateral lemniscus to the temporal lobe; and
 * (4) fibers which pass from the occipital and temporal lobes to the nuclei pontis.
