Wikipedia
Pineal gland
The pineal gland, conarium, or epiphysis cerebri, is a small endocrine gland in the brain of most vertebrates. The pineal gland produces melatonin, a serotonin-derived hormone which modulates sleep patterns in both circadian and seasonal cycles. The shape of the gland resembles a pine cone, which gives it its name. The pineal gland is located in the epithalamus, near the center of the brain, between the two hemispheres, tucked in a groove where the two halves of the thalamus join. The pineal gland is one of the neuroendocrine secretory circumventricular organs in which capillaries are mostly permeable to solutes in the blood.Nearly all vertebrate species possess a pineal gland. The most important exception is a primitive vertebrate, the hagfish. Even in the hagfish, however, there may be a "pineal equivalent" structure in the dorsal diencephalon. The lancelet Branchiostoma lanceolatum, an early chordate which is a close relative to vertebrates, also lacks a recognizable pineal gland. The lamprey (another primitive vertebrate), however, does possess one. A few more complex vertebrates have lost pineal glands over the course of their evolution.The results of various scientific research in evolutionary biology, comparative neuroanatomy and neurophysiology have explained the evolutionary history (phylogeny) of the pineal gland in different vertebrate species. From the point of view of biological evolution, the pineal gland is a kind of atrophied photoreceptor. In the epithalamus of some species of amphibians and reptiles, it is linked to a light-sensing organ, known as the parietal eye, which is also called the pineal eye or third eye.René Descartes believed the human pineal gland to be the "principal seat of the soul". Academic philosophy among his contemporaries considered the pineal gland as a neuroanatomical structure without special metaphysical qualities; science studied it as one endocrine gland among many.

pineal gland
The pineal gland is a small, pea-sized endocrine gland in the brain of most vertebrates. It produces and regulates some hormones, including melatonin which influences the sleep-wake cycle. The gland has been linked to a variety of functions including regulation of circadian rhythms, mood, and immune system. It is located near the center of the brain between the two hemispheres.

Pineal gland
The pineal gland is a small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns and seasonal functions. Its shape resembles a tiny pine cone, and it is located near the centre of the brain, between the two hemispheres, tucked in a groove where the two rounded thalamic bodies join. Nearly all vertebrate species possess a pineal gland. The most important exception is the hagfish, which is often thought of as the most primitive type of vertebrate. Even in the hagfish, though, there may be a "pineal equivalent" structure in the dorsal diencephalon. The lancelet amphioxus, the nearest existing relative to vertebrates, also lacks a recognizable pineal gland. The lamprey, however, does possess one. A few "higher" types of vertebrates, including the alligator, lack pineal glands because they have been lost over the course of evolution.
The Nuttall Encyclopedia
Pineal Gland
a small cone-shaped body of yellowish matter in the brain, the size of a pea, and situated in the front of the cerebellum, notable as considered by Descartes to be the seat of the soul, but is now surmised to be a rudimentary remnant of some organ, of vision it would seem, now extinct.
U.S. National Library of Medicine
Pineal Gland
A light-sensitive neuroendocrine organ attached to the roof of the THIRD VENTRICLE of the brain. The pineal gland secretes MELATONIN, other biogenic amines, and neuropeptides.
