The diencephalon of the brain consists of structures that are lateral to the third ventricle, and includes the thalamus, the hypothalamus, the epithalamus and the subthalamus.

The diencephalon is one of the main vesicles of the brain formed during embryogenesis. During the third week of development a neural tube is created from the ectoderm - one of the three primary germ layers. The tube forms three main vesicles during the third week of development - the prosencephalon, the mesencephalon and the rhombencephlaon. The prosencephlon gradually divides into the telencephalon and the diencephalon.

Structure

Location of the Diencephalon (red).

The diencephalon consists of the following structures:

Thalamus
Hypothalamus including the Neurohypophysis
Epithalamus which consists of

Anterior and Posterior Paraventricular nuclei

Medial and lateral Habenular nuclei

Stria medullaris thalami

Posterior commissure

Pineal body

Subthalamus

Attachments

The optic nerve (CNII) attaches to the diencephalon. The optic nerve is a sensory (afferent) nerve responsible for vision; it runs from the eye through the optic canal in the skull and attaches to the diencephalon. The retina itself is derived from the optic cup, a part of the embryonic diencephalon.

Function

The diencephalon is the region of the embryonic vertebrate neural tube that gives rise to anteriorforebrain structures including the thalamus, hypothalamus, posterior portion of the pituitary gland, and pineal gland. The hypothalamus performs numerous vital functions, most of which relating directly or indirectly to the regulation of visceral activities by way of other brain regions and the autonomic nervous system.

Serotonergic cells are among the earliest neurons to be born in the developing central nervous system and serotonin is known to regulate the development of the nervous system. One of the major targets of the activity of serotonergic cells is the serotonin 1A receptor (5-HT1A), an ancestral archetypi
