			The '''supratentorial region''' is an anatomical area of the [[human brain]] located above the [[tentorium cerebelli]]. This region encompasses the majority of the [[cerebrum]], including the [[cerebral cortex]], [[basal ganglia]], and the [[thalamus]]. It is a critical area involved in higher cognitive functions, sensory perception, and voluntary motor activities.

	The supratentorial region is divided into two main parts: ~~the cerebral hemispheres and the diencephalon.

			* The [[parietal lobe]] processes sensory information such as touch, temperature, and pain.
			* The [[temporal lobe]] is important for auditory processing and memory.

'''Supratentorial region''' is a term in [[anatomy]] that refers to the area located above the [[tentorium cerebelli]], a fold of [[dura mater]] in the brain. This region includes the [[cerebral hemispheres]] (most of the brain's mass) and the [[diencephalon]]. The term "supratentorial" comes from the Latin words "supra," meaning above, and "tentorium," which refers to the tentorium cerebelli.

== Anatomy ==

The supratentorial region is divided into two main parts: the cerebral hemispheres and the diencephalon. The cerebral hemispheres are further divided into the [[cerebral cortex]], [[basal ganglia]], and [[limbic system]]. The diencephalon includes the [[thalamus]] and [[hypothalamus]].

=== Cerebral Hemispheres ===

The cerebral hemispheres are the largest part of the brain and are responsible for higher brain functions, including thought, emotion, and action. The cerebral cortex, the outer layer of the cerebral hemispheres, is involved in cognitive functions such as memory, attention, consciousness, thought, language, and awareness.

=== Diencephalon ===

The diencephalon is located beneath the cerebral hemispheres and includes the thalamus and hypothalamus. The thalamus acts as a relay station for sensory information, while the hypothalamus is involved in various functions, including the regulation of body temperature, hunger, thirst, and sleep.

== Clinical Significance ==

Conditions that affect the supratentorial region can have significant effects on a person's cognitive and physical abilities. These conditions can include [[stroke]], [[brain tumor]], [[traumatic brain injury]], and various [[neurodegenerative diseases]]. Treatment for these conditions often involves [[neurosurgery]], which can be challenging due to the complex anatomy of the supratentorial region.
