The epithalamus is a (dorsal) posterior segment of the diencephalon. The diencephalon is a part of the forebrain that also contains the thalamus, the hypothalamus and pituitary gland.[1] The epithalamus includes the habenula and their interconnecting fibers, the habenular commissure, the stria medullaris and the pineal gland.
Functions
The function of the epithalamus is to connect the limbic system to other parts of the brain. Some functions of its components include the secretion of melatonin and secretion of hormones from pituitary gland by the pineal gland circadian rhythms), and regulation of motor pathways and emotions.
Components
The epithalamus comprises the habenular trigone, the pineal gland, and the habenular commissure. It is wired with the limbic system and basal ganglia.
Species that possess a photoreceptive parapineal organ show asymmetry in the epithalamus at the habenula, to the left (dorsal).[2]
Dysfunction
Dysfunction of the epithalamus can be related to mood disorders, such as major depression, schizophrenia and sleeping disorders. Other symptoms include severe anxiety, sleep disturbance and choroid plexus cysts, indicating that Foxg1 likely plays a role in epithalamic development.[3]
Mood disorders
Sleep disorders
