Exploration of the brain from its superior aspect
Lentiform nucleus, internal capsule, subthalamic nucleus
A horizontal cut has been made through the lentiform nucleus, internal capsule and thalamic area. The lamination within the lentiform nucleus is still demonstrable, although some of the nucleus was removed earlier. From the medial border of the globus pallidus fibers of the fasciculus lenticularis (13) pass through the internal capsule. The subthalamic nucleus (corpus Luysi) is cut through (14). The geniculate bodies are still present in this section which is cut lower than the previous view.
