A parietal eye (third eye, pineal eye) is a part of the epithalamus in some vertebrates. The eye is at the top of the head; is photoreceptive; and is associated with the pineal gland , which regulates circadian rhythmicity and hormone production for thermoregulation . [ 1 ]
The pineal gland is present in almost all vertebrates, but is absent in protochordates in which there is a simple pineal homologue. The hagfish, archaic vertebrates, lack a pineal gland. [7] In some species of amphibians and reptiles, the gland is linked to a light-sensing organ, variously called the parietal eye, the pineal eye or the third ...
Adherents of theosophist H. P. Blavatsky have suggested that the third eye is in fact the partially dormant pineal gland, which resides between the two hemispheres of the brain. [6] Reptiles and amphibians sense light via a third parietal eye —a structure associated with the pineal gland—which serves to regulate their circadian rhythms ...
Walter Baldwin Spencer at the University of Oxford was the first to recognize pineal gland and its associated structure in lizards. In 1886, he found that the pineal tissue in some species were connected to an eye-like structure which he called the pineal eye or parietal eye, as they were associated with the parietal foramen and the pineal ...
“Iolite is a beautiful purple-blue gemstone that is often associated with the third eye chakra, the site of our pineal gland,” Salzer says. “Iolite is said to release addictions and enhance ...
In the living tuatara and some lizards, as well as in many fossil tetrapods, a small opening, the parietal foramen (also called the pineal foramen), is present between the two parietal bones at the midline of the skull. This opening is the location of the parietal eye (also called the pineal or third eye), which is much smaller than the two ...
The epithalamus is a tiny structure that 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).
An abundance of cilia and centrioles has also been found in these Type 2 cells of the pineal gland. [7] Unique to the Type 2 is the presence of vacuoles containing 2 layers of membrane. [7] As Type 1 cells contain serotonin, Type 2 cells contain melatonin and are thought to have similar characteristics as endocrine and neuronal cells. [8]
