This is one of the most important components of the central nervous system (CNS), as all neuronal transmissions that pass through the body, throughout the peripheral nervous system (PNS) to the CNS are relayed must at … The thalamus is a paired gray matter structure of the diencephalon located near the center of the brain. Rather, it examines assumptions, and discerns hidden values, evaluates evidence, & assesses conclusions. an almond-shaped neural structure in the anterior part of the temporal lobe of the cerebrum; intimately connected with the hypothalamus and the hippocampus and the cingulate gyrus; as part of the limbic system it plays an important role in motivation and emotional behavior It is the oldest part of our brain and is located deep within our head and on top of our spinal cord, it controls most of our most basic functions. The thalamus then relays these signals to various areas of the cerebral cortex.

In turn, the thalamus sends a signal to the automatic nervous system thereby producing a physiological response. The thalamus, which is a sensory “way-station” for the rest of the brain, is primarily important due to its connections with other limbic-system structures. Most of the process occurs on the back of the eye called the retina. Learn about the definition, parts, and functions of the sensory system. Being awake is the opposite of the state of being asleep in which most external inputs to the brain are excluded from neural processing. The thalamus, which is dual lobed and composed of gray matter, is involved in the regulation of motor functions in the body and in sensory perception. All sensory modalities (vision, taste, general and visceral sensation, auditory, etc.) The main and primary function of the thalamus is to relay motor and sensory signals to the cerebral mantle.

Specifically, the thalamus works to send neuronal transmissions to the brain for the regulation of the Circadian rhythm in order to suppress the body’s response to sensation such as sound during sleep. The thalamus plays a part in motor control by providing positive reinforcement of movements initiated in the motor cortex. The thalamus (from the Greek word meaning “chamber”) is centrally located between the cerebral cortex and the midbrain and is known for its role in relaying sensory and motor signals to the cerebral cortex, and the regulation of sleep, consciousness, and alertness—rather like a hub of information flow from the senses to the cortex.
