Deep Brain Structures, Superior View

Description

Basal ganglia and diencephalic landmarks dominate this superior view of the brain’s deep internal architecture. Paired thalami sit near the midline, their superior surfaces bordering the roof of the third ventricle, while the caudate nuclei arc anteroposteriorly along the lateral margins of the lateral ventricles. Lateral to the caudate, the putamen and globus pallidus form the lentiform nucleus, separated from the medial deep nuclei by the internal capsule, a dense white matter corridor that defines the medial-lateral relationships across the subcortical compartment. Parkinson disease, dystonia, and essential tremor all map onto circuits that traverse these exact structures, so an unambiguous top-down arrangement of striatum, pallidum, internal capsule, and thalamus matters in both teaching and operative planning. The superior perspective is also the most intuitive bridge to axial neuroimaging, where the internal capsule’s position between thalamus medially and lentiform nucleus laterally explains classic lacunar infarct syndromes and their motor deficits. Orientation is the lesson. Neuroanatomy faculty often pair this illustration with axial MRI or CT to reinforce how the basal ganglia and thalamus appear slice-by-slice, and it fits cleanly into chapters on the diencephalon, extrapyramidal pathways, and ventricular anatomy. Neuroscience publishers and neurosurgical educators will also find it well suited for discussions of deep brain stimulation targets (subthalamic region and globus pallidus internus) and thalamic nuclei relevant to tremor control, with the internal capsule highlighted as the nearby structure you cannot injure.
