The diencephalon includes the hypothalamus and the thalamus. This condition is usually found in infants and young children and may result in symptoms including failure to gain weight and grow normally (failure to thrive), progressive thinness and weakness (emaciation), and hyperactivity and restlessness (hyperkinesia).
What would happen if the diencephalon is damaged?
Specifically, the diencephalon may serve as a link between limbic and cortical structures, and damage to the diencephalon can contribute to amnesia through what has been called a “disconnection syndrome” (Warrington and Weiskrantz 1982; Markowitsch 1988; Aggleton and Brown 1999).

What is the function of the thalamus?
The thalamus assists in sensory perception, motor function regulation, and sleep cycle control. The thalamus acts as a relay station for almost all sensory information (with the exception of smell). Before sensory information reaches your brain's cortex, it stops at the thalamus. The thalamus processes information and passes it along. Input information then travels to the correct area of specialty and is passed to the cortex for further processing. The thalamus also plays a big role in sleep and consciousness.

This brain region has a central location within the brain, it is located between the cerebral hemispheres and the brain stem , and through it travel most of the fibers that go to the cerebral cortex. The diencephalon, unlike the telencephalon that ends up forming the cerebral cortex and other internal structures such as ...
What is the largest structure in the diencephalon?
The thalamus. The thalamus corresponds to one of the largest structures in the diencephalon. It is made up mainly of grey matter, rich in neuronal bodies. Nerve impulses pass through the thalamus from the central nervous system to the peripheral and vice versa, this being the place where sensory signals are integrated for subsequent interpretation ...

The epithalamus is a dorsal part of the diencephalon, which is formed mainly by the habenulas -cellular nuclei with limbic and motor functions- and the pineal gland. It has important functions within the limbic system, connecting it with other parts of the brain, which for example include controlling the circadian rhythm through the pineal gland.

This structure is differentiated ...
Which part of the body controls the endocrine system?
The hypothalamus is considered one of the largest centers of endocrine control of the human body.. The signals that this part of the diencephalon emits condition a large amount of hormones in the endocrine system, thanks to the release of hormones that they cause in the pituitary gland, also known as the pituitary gland. 2.

What is the diencephalon?
The diencephalon is deep beneath the cerebrum and constitutes the walls of the third ventricle. The diencephalon can be described as any region of the brain with “thalamus” in its name. The major regions of the diencephalon are the thalamus itself, the hypothalamus, the epithalamus, which contains the pineal gland, and the subthalamus, which includes part of the basal nuclei (Figure 12.4. 1 ).

What is the midbrain?
Midbrain. The mesencephalon, one of the original region of the embryonic brain, becomes the midbrain, a small region between the thalamus and pons. The cerebral aqueduct passes through the center of the midbrain, such that these regions are the roof and floor of that canal.
Which part of the brain sends information to the thalamus?
The cerebrum also sends information down to the thalamus, which usually communicates motor commands. This involves interactions with the cerebellum and other nuclei in the brainstem. Inferior to the thalamus lies the subthalamic nucleus, which is part of the basal nuclei.
