Anatomical terms of neuroanatomy

The diencephalon ("interbrain") is the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain structures. In development, the forebrain or prosencephalon, is the most anterior vesicle of the neural tube that later forms both the diencephalon and the telencephalon (which develops into the cerebrum). The diencephalon develops into three central brain structures between the brainstem and the cerebrum – the thalamus, the hypothalamus, and the pituitary gland.[1]

Structure[edit]

Location of the Diencephalon (red).


Attachments[edit]

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[edit]

The diencephalon is the region of the embryonic vertebrate neural tube that gives rise to posterior forebrain 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.
