Forebrain In the anatomy of the brain of vertebrates, the forebrain or prosencephalon is the rostral-most (forward-most) portion of the brain. The forebrain, the midbrain (mesencephalon), and hindbrain (rhombencephalon) are the three primary portions of the brain during early development of the central nervous system.It controls body temperature, reproductive functions, eating, sleeping, and any display of emotions.he forebrain, the midbrain (mesencephalon), and hindbrain (rhombencephalon) are the three primary portions of the brain during early development of the central nervous system.

- The diencephalon relays sensory information between brain regions and controls many autonomic functions of the peripheral nervous system. It also connects structures of the endocrine system with the nervous system and works in conjunction with limbic system structures to generate and manage emotions and memories.

The Diencephalon The diencephalon, or interbrain, is located between the cerebral hemispheres and the brain stem. One can see it by cutting into the central section of the brain. The diencephalon includes the thalamus and the hypothalamus. (Fig. 6-10.) The two parts of the thalamus form the lateral walls of the third ventricle (see Figs.

Overview Anencephaly is a serious developmental defect of the central nervous system in which the brain and cranial vault are grossly malformed. The cerebrum and cerebellum are reduced or absent, but the hindbrain is present. Anencephaly is a part of the neural tube defect (NTD) spectrum. This defect results when the neural tube fails to close during the third to fourth weeks of development, leading to fetal loss, stillbirth, or neonatal death.

7 Things You Should Do in Skyrim Once you get there, proceed to the Throat of the World, the highest mountain in Skyrim and follow it all the way to the top. If you can. 3. Track down all 13 Guardian Stones. One of the most exciting things about Skyrim is that it doesn't try to shoehorn you into a certain character class. You don't need to decide to be a warrior, a wizard, or a thief; your actions will determine the way you progress in the game.

Cerebrum The dorsal telencephalon gives rise to the pallium (cerebral cortex in mammals and reptiles) and the ventral telencephalon generates the basal ganglia. The diencephalon develops into the thalamus and hypothalamus, including the optic vesicles (future retina).he cerebrum is the newest structure in the phylogenetic sense, and in mammals it is the largest and most developed, out of all known species. The cerebrum is made up of the two cerebral hemispheres and their cortices, (the outer layers of gray matter), and the underlying regions of white matter.

- The midbrain, also called the mesencephalon, is a small region of the brain that serves as a relay center for visual, auditory, and motor system information. It regulates autonomic functions, those that the body carries out without conscious thought, such as digestion, heart rate, and breathing rate.

Midbrain From Wikipedia, the free encyclopedia. The midbrain or mesencephalon (from the Greek mesos, middle, and enkephalos, brain) is a portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.he mesencephalon is considered part of the brainstem. Its substantia nigra is closely associated with motor system pathways of the basal ganglia. The human mesencephalon is archipallian in origin, meaning that its general architecture is shared with the most ancient of vertebrates.
