Brain Intermediate (Diencephalon)

The diencephalon is a part of the forebrain consisting of the epithalamus, thalamus (posterior thalamus) and hypothalamus. The diencephalon is one of the divisions of the brain. It is located between the midbrain and medulla oblongata. It includes:

  1. Epithalamus - responsible for regulating sleep, appetite and body temperature.

  2. The thalamus is a relay center through which all sensory impulses (with the exception of olfactory) pass to the cerebral cortex.

  3. Hypothalamus - regulates the autonomic functions of the body, such as drinking, eating, body temperature. Responsible for emotions and motivational behavior.

Thus, the diencephalon plays an important role in the regulation of basic physiological processes and behavior. It is closely connected with other parts of the brain.



The intermediate brain or diencephalon (diencephalon, from the Greek di- “two” + enkephalon “brain”) is the part of the forebrain located between the brain stem and the cerebellum. It consists of two main structures: the thalamus and hypothalamus, as well as a small section of the epithalamus.

The epithalamus (epi- "above" + thalamus "thalamus") is a small region of the forebrain located above the thalamus. It is important for regulating sleep and wakefulness, as well as coordinating the movements of the eyeballs.

The thalamus (thalamus “thalamus” - thalamic complex) is the largest structure of the diencephalon. It has many functions, including regulating sensory signals, coordinating eye muscle movements, and regulating the autonomic nervous system. The thalamus also plays an important role in processing pain signals.

The hypothalamus (Greek: hypo- "under" + thalamus "thalamus"), also known as the subthalamic region, is the lowest part of the diencephalon and is located beneath the thalamus and epithalamus. The hypothalamus plays a key role in the regulation of the endocrine system, providing communication between the central nervous system and the endocrine glands. It is also responsible for regulating body temperature and homeostasis.

Thus, the diencephalon plays an important role in many processes associated with the regulation and coordination of body functions.



The diencephalon, or partly the midbrain, consists of two regions of the hindbrain - the thalamus and the periventricular substance (PVB), connected at the lower trunk of the diencephalon.

The posterior thalamus is a nerve center that processes incoming impulses and also helps transmit signals related to movement and balance from the spinal cord to the medulla oblongata and cerebellum. The hypothalamus regulates many functions, including maintaining homeostasis in the body. The epithalamus is part of the midbrain. Participates in the formation of motor reactions, activates
