All human senses apart from the smell are primarily regulated by the thalamus, which is positioned on the topmost part of the brain stem.

It obtains the information from all our senses apart from the smell and passes it to other districts of the brain that keep track of such senses like touch, eyesight, hearing, and taste.

The thalamus takes the shape of a not very large region of the brain is accountable for passing various sensory warnings to the cerebral cortex.

Thalamus has special nerve links with various areas of the brain.

The major role performed by the thalamus is not simply the control of sensory signals transferred to the cerebral cortex, but also the regulation of our motor activity.

As such, this brain area is largely responsible for sleep patterns, alertness and such aspects as wakefulness.

The thalamus is positioned on the roof of the brain stem not far from the center of our brain being linked to a myriad of nerves and neurons as part of the brain structure.

It is separated into a pair of large masses, and each serves its own role.

In general, the thalamus plays a major role in controlling our sensory perceptions and regulates the proper functioning of all senses apart from the smell.

It consists of various areas and branches that help it to perform its major task.

These include such areas as allothalamus and isothalamus.

It also contains the nerve fibers that divide the thalamus into separate parts.
