	Diencephalon - Wikipedia, the free encyclopedia
		The diencephalon is the region of the brain that includes the thalamus, hypothalamus, epithalamus, prethalamus or subthalamus and pretectum.
		The diencephalon is located at the midline of the brain, above the mesencephalon of the brain stem.
		The diencephalon contains the zona limitans intrathalamica as morphological boundary and signalling centre between the prethalamus and the thalamus.

	Physiology III Neuroscience - Diencephalon & Forebrain
		The diencephalon includes the dorsal thalamus, hypothalamus, ventral thalamus, and the epithalamus, and it is situated between the telencephalon and the brainstem.
		In general, the diencephalon is the main processing center for information destined to reach the cerebral cortex from all ascending sensory pathways (except those related to olfaction) and numerous other subcortical cell groups.
		In the diencephalon, the main limbic structures are the hypothalamus and the anterior nucleus of the thalamus.

		• The diencephalon lies rostral to the brainstem, begins at the level of the posterior commissure and extends to the interventricular foramina, includes the structures surrounding the third ventricle, and is subdivided into four parts.
		The space within the fissure is occupied by the vascular tela choroidea which is continuous with the vascular core of the choroid plexus of the lateral and third ventricles.
		The body is attached to the diencephalon by the pineal stalk, into which te 3rd ventricle extends as the pineal recess.

		The "hypothalamus" serves as a link between the nervous and endocrine systems, and is connected to the cerebral cortex, thalamus, and other parts of the brain stem so that it can receive impulses from them and send impulses to them.

		The hypothalamus and other areas of the diencephalon have also been shown to be involved in the selective engagement and disengagement of certain cortical areas associated with specific cognitive tasks such as language [2].
		The diencephalons is necessary in continuously engaging parts of the cortex associated with lexical-semantic information, therefore damage to these areas will cause an inability to maintain the circuit preventing proper consolidation of the information from STM into long- term memory (LTM) [2,3].
		The subcortex diencephalon, which is comprised of the thalamus, hypothalamus, and subthalamus, is integral to many important functions that control the workings of the body, in turn influencing behavior.

		Introduction A variety of ablation studies have implicated the posterior basal diencephalon in the promotion of wakefulness, specifically its role may be to produce behavioral arousal, a component of wakefulness.
		Consequently, in the current study, long term recordings of decerebrate rats with and without an intact posterior basal diencephalon and instrumented with additional recording leads were performed to test the hypothesis that removal of the posterior basal diencephalon completely eliminates wakefulness.
		The animals were then anesthetized, the posterior basal diencephalon was removed at its junction with the midbrain, and animals were monitored for another 4-6 hours.

	Lesson 3: Lecture 5 Transcript
		Again, as we talked about in earlier lectures, encephalon means brain, and the first part of the word relates to the brain structure we’re talking about.
		In conclusion, the diencephalon (as we see in slide eight) is an older brain structure, but it is extremely, extremely important for normal functioning, and when you damage particular structures within it, the symptoms are pronounced.
		Well now we’ve talked a little bit about the diencephalon, let’s move on and talk about the next major group of structures called the telencephalon.

		The surface of the cerebrum is composed of gray matter 2 to 4 mm thick and is called the cerebral cortex; beneath the cortex is the cerebral white matter.
		The basal nuclei control large automatic movements of skeletal muscles, such as swinging the arms while walking and are concerned with the regulation of muscle tone required for specific body movements.
		The limbic system is a ring of structures on the inner border of the cerebrum and floor of the diencephalon that encircle the brain stem.

		Definition: The diencephalon is the posterior part of the forebrain.
		Structure: The diencephalon, the posterior part of the forebrain, includes the thalamus, the pineal gland, and the hypothalamus.
		In amphibians, the pineal gland is not known to be important, and the hypothalamus regulates the autonomic (visceral) nervous system, and the endocrine systems, through the hypophysis.

		In the 5th week, when the embryo reaches the 7 mm stage, the simple plan of the prosencephalon changes; paired telencephalic vesicles and the diencephalon begin to form; the optic cup continues its development.
		An early separation of the telencephalon and diencephalon occurs through a shallow tele-diencephalic sulcus which deepens and persists in the adult as the horizontal transverse cerebral fissure (filled with duplicated pia and blood vessels, called velum interpositum).
		As development progresses the growing hemispheres continue their caudal expansion so as to cover the mesencephalon and more.
