Detailed explanation-1: -The thalamus carries messages from the sensory organs like the eyes, ears, nose, and fingers to the cortex.

Detailed explanation-2: -The thalamus serves as a relay station for almost all information that comes and goes to the cortex. It plays a role in pain sensation, attention and alertness.

Detailed explanation-3: -Your thalamus is an egg-shaped structure in the middle of your brain. It’s known as a relay station of all incoming motor (movement) and sensory information-hearing, taste, sight and touch (but not smell)-from your body to your brain.

Detailed explanation-4: -From the eye to the brain The axons of ganglion cells exit the retina to form the optic nerve, which travels to two places: the thalamus (specifically, the lateral geniculate nucleus, or LGN) and the superior colliculus. The LGN is the main relay for visual information from the retina to reach the cortex.

Detailed explanation-5: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.
