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. FunctionsThe 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 glandcircadian rhythms), and regulation of motor pathways and emotions. ComponentsThe 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] References1. ^{{cite book|title=Biological Psychology|last=Klein|first= Stephen B.|last2=Thorne|first2= B.
