A collection of cell body clusters located in the middle of the forebrain.

The thalamus is a relatively large collection of cell body clusters shaped like two small footballs. It is involved in receiving sensory information from the eyes and other sense organs, processing that information, and then transmitting it to primary sensory zones in the cerebral cortex. The thalamus also processes pain signals from the spinal cord as well as information from different parts of the cerebral hemispheres, and relays it to the cerebellum and the medulla. Together with the hypothalamus, the thalamus forms part of the forebrain called the diencephalon.

By registering the sensory properties of food, such as texture and temperature, the thalamus plays a role in...
