Pulvinar nucleus of thalamus
WebMay 1, 2024 · The pulvinar is densely connected both structurally and functionally to various cortical regions, including occipital, parietal, temporal, and prefrontal cortices (56, 57). The dorsomedial thalamus has similar cortical connections as well as both direct and indirect projections to the amygdala (58, 59). The thalamus is a paired structure of gray matter located in the forebrain which is superior to the midbrain, near the center of the brain, with nerve fibers projecting out to the cerebral cortex in all directions. The medial surface of the thalamus constitutes the upper part of the lateral wall of the third ventricle, and is connected to the corresponding surface of the opposite thalamus by a flattened gray band, the interthalamic adhesion. The lateral part of the thalamus is the phylogenet…
