Thalamus

The thalamus (from Greek θάλαμος, "chamber") is a large mass of gray matter located in the dorsal part of the diencephalon (a division of the forebrain). Nerve fibers project out of the thalamus to the cerebral cortex in all directions, allowing hub-like exchanges of information. It has several functions, such as the relaying of sensory signals, including motor signals to the cerebral cortex and the regulation of consciousness, sleep, and alertness.

Anatomically, it is a paramedian symmetrical structure of two halves (left and right), within the vertebrate brain, situated between the cerebral cortex and the midbrain. It forms during embryonic development as the main product of the diencephalon, as first recognized by the Swiss embryologist and anatomist Wilhelm His Sr. in 1893.

Examples of use of Thalamus

3. "This connects the orbito–frontal cortex – which is more related to emotion, assessing of certain situations – to the thalamus, which is the big relay station of the brain," Dr Malizia said.
4. Ventral anterior capsule A region of the brain that connects the frontal cortex, which deals with emotion, to the thalamus, which processes information from the senses and transmits it to the other parts of the brain.
5. A magnetic resonance imaging test revealed that he had suffered two small strokes involving adjacent areas of the thalamus involved in processing sensory signals such as pain and pressure.
