What is the function of the diencephalon?from thoughtco.com
The diencephalon is the region of the brain that relays sensory information and connects components of the endocrine system with the nervous system. The diencephalon regulates a number of functions including autonomic, endocrine, and motor functions. It also plays a major role in sensory perception. Components of the diencephalon include: 1 Thalamus: A limbic system structure that connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and spinal cord. The thalamus also plays a role in the control of sleep and wake cycles. 2 Hypothalamus: Acts as the control center for many autonomic functions including respiration, blood pressure, and body temperature regulation. This endocrine structure secretes hormones that act on the pituitary gland to regulate biological processes including metabolism, growth, and the development of reproductive system organs. As a component of the limbic system, the hypothalamus influences various emotional responses through its influence on the pituitary gland, skeletal muscular system, and autonomic nervous system. 3 Pineal Gland: This small endocrine gland produces the hormone melatonin. Production of this hormone is vital to the regulation of sleep-wake cycles and also influences sexual development. The pineal gland converts nerve signals from the sympathetic component of the peripheral nervous system into hormone signals, thereby linking the nervous and endocrine systems.

The tectum lies dorsal to the tegmentum and cerebral aqueduct, and it contains the nuclei of the superior and inferior colliculi.
