The thalamus is a part of the brain. It is located in the center of the brain, beneath the cerebral hemispheres and next to the third ventricle. It is formed of grey matter and can be thought of as a relay station for nerve impulses in the brain.

The thalami are prominent bulb-shaped regions, typically slightly more than 1 cm in length in humans, located in the center of the brain. They form on each side of the paleopalliar diencephalon that emerges from the mammalian prosencephalon. The thalamus is largely made of nuclear groups that relate to specific functions in the cerebrum. Thalamic nuclei have subcortical projections, and can be classified as either relay nuclei or association nuclei (see below). Thalamic nuclei also have strong reciprocal connections with the cerebral cortex, forming cortico-thalamo-cortical recurrent loops that are believed may be involved with consciousness.

Cerebral hemisphere: The cerebral hemisphere forms each half of a brain the left and right. Humans (and many other types of animals) have a brain divided into two hemispheres. Each hemisphere has corresponding structures, and structural locations; however, they are not mirror images. Instead, the hemispheres usually ar...

Third ventricle: The third ventricle is one of the four connected fluid-filled cavities within the human brain. It is a median cleft between the two thalami, and is filled with cerebrospinal fluid (CSF)....
