The pineal body, known to regulate sleep patterns in humans, is thought to produce the hormones involved in hibernation and aestivation in amphibians.

' Basing his reasoning on his belief that all the enzymatic material needed to produce DMT is found in the pineal gland ( see evidence in mammals ), and moreover in substantially greater concentrations than in any other part of the body, Strassman ( p. 69 ) has speculated that DMT is made in the pineal gland.

Descartes argued that the mind interacts with the body at the pineal gland.

He believed the cerebrospinal fluid of the ventricles acted through the nerves to control the body, and that the pineal gland influenced this process.

* Endocrine system: communication within the body using hormones made by endocrine glands such as the hypothalamus, pituitary gland, pineal body or pineal gland, thyroid, parathyroids and adrenals, i. e., adrenal glands.

In his letter to Elisabeth of Bohemia, Princess Palatine, he suggested that animal spirits interacted with the body through the pineal gland, a small gland in the centre of the brain, between the two hemispheres.

According to Max Heindel's Rosicrucian writings, called Western Wisdom Teachings, the third eye is localized in the pituitary body and the pineal gland.

The pineal gland ( also called the pineal body, epiphysis cerebri, epiphysis, conarium or the " third eye ") is a small endocrine gland in the vertebrate brain.

The pineal body consists in humans of a lobular parenchyma of pinealocytes surrounded by connective tissue spaces.

The pineal gland was then thought to be the very place at which the mind would interact with the mortal and machine-like body.

described how it is the pineal gland, or the Ajna Chakra, that takes over the functioning of the body in the natural state, as opposed to thought.

Descartes, for example, suggested that the pineal gland, a midline unpaired structure in the brain of many organisms, was the point of contact between mind and body.

The SCN sends information to other hypothalamic nuclei and the pineal gland to modulate body temperature and production of hormones such as cortisol and melatonin.

This is also true of most brain abnormalities, though there are exceptions such as a calcified tumour ( e. g. meningioma, craniopharyngioma, some types of glioma ); whilst calcification in such normal structures as the pineal body, the choroid plexuses, or large brain arteries may indirectly give important clues to the presence of structural disease in the brain itself.

The epithalamus is a ( dorsal ) posterior segment of the diencephalon ( a segment in the middle of the brain also containing the hypothalamus and the thalamus ) which includes the habenula and their interconnecting fibers the habenular commissure, the stria medullaris and the pineal body.

The epithalamus comprises the trigonum habenulæ, the pineal body, and the posterior commissure.

Now, as you exhale, visualize the cosmic solar energy flowing down the pineal gland and spreading throughout your body with a revitalizing effect.

Descartes originally claimed that consciousness requires an immaterial soul, which interacts with the body via the pineal gland of the brain.

The pineal gland was also used in Descartes's explanation of Cartesian Dualism as the " seat of the soul " and the connection between the material and immaterial world.

They are created by an abnormal and uncontrolled cell division, usually in the brain itself, but also in lymphatic tissue, in blood vessels, in the cranial nerves, in the brain envelopes ( meninges ), skull, pituitary gland, or pineal gland.

The hormones DHEA ( a steroid ), pregnenolone ( also a steroid ) and the pineal hormone melatonin are marketed as dietary ingredients in supplements in the US.

Green Iguanas have a white photosensory organ on the top of their heads called the parietal eye ( also called third eye, pineal eye or pineal gland ), in contrast to most other lizards, which have lost it.

The term " Cartesian dualism " is also often associated with this more specific notion of causal interaction through the pineal gland.

These petals also represent the manifest and unmanifest mind, and are said by some to represent the pineal and pituitary glands.

In certain cases, the pineal gland is also affected ( trilateral retinoblastoma ).

Axelrod also made major contributions to the understanding of the pineal gland and how it is regulated during the sleep-wake cycle.

It has also been linked to paranormal activities, and Rick Strassman has argued that it triggers the release of DMT from the pineal gland, causing a dreaming state.

CNG channels were also found in cone photoreceptors, chemo sensitive cilia of olfactory sensory neurons, and the pineal gland.

Dr. Strassman has also noted that the pineal gland first becomes visible at approximately the forty-ninth day of fetal development, nearly exactly the same moment that the gender of the fetus can first be determined.

Blue Iguanas have evolved a white photosensory organ on the top of their heads called the parietal eye ( also known as the third eye, pineal eye or pineal gland ).

First, the soul is unitary, and unlike many areas of the brain the pineal gland appeared to be unitary ( though subsequent microscopic inspection has revealed it is formed of two hemispheres ).

The pineal gland is a midline structure shaped like a pine cone, and is often seen in plain skull X-rays, as it is often calcified ; calcification has been shown in one small study to correlate with the accumulation of fluoride.

The brain has a pineal gland, a feature formerly thought to be absent in the owls .< ref > Birds show variation in the melatonin concentration between day and night.

Dr. Strassman has conjectured that when a person is approaching death or possibly when in a dream state, the pineal gland releases DMT in a relatively large amount, accounting for much of the imagery reported by survivors of near-death experiences.

These ganglion cells, which contain melanopsin, convey their signals to the " circadian clock " via the retinohypothalamic tract ( distinct from the optic nerve ), linking the retina to the pineal gland.

Pinealocytes are the main cells of the pineal gland.

In non-mammalian vertebrates, melanopsin is found in a wider subset of retinal cells, as well as in photosensitive structures outside the retina such as the iris muscle of the eye, deep brain regions, the pineal gland, and the skin.

Many formulations have forms of fluoride attached to assist in permeating the blood – brain barrier, which is suspected as a factor in pineal gland effects.

Another theory is that the cause may be related to melatonin which is produced in dim light and darkness by the pineal gland, since there are direct connections, via the retinohypothalamic tract and the suprachiasmatic nucleus, between the retina and the pineal gland.

Technically, Kundalini energy is understood as being sparked during yogic breathing when prana and apana blends at the 3rd chakra ( naval center ) at which point it initially drops down to the 1st and 2nd chakras before traveling up to the spine to the higher centers of the brain to activate the golden cord-the connection between the pituitary and pineal glands-and penetrate the 7 chakras.

Blavatsky and Rick Strassman, have suggested that the third eye is in fact the partially dormant pineal gland, which resides between the two hemispheres of the brain.

Various types of lower vertebrates, such as reptiles and amphibians, can actually sense light via a third parietal eye — a structure associated with the pineal gland — which serves to regulate their circadian rhythms, and for navigation, as it can sense the polarization of light.

Melatonin, produced in the pineal gland which is outside of the blood – brain barrier, acts as an endocrine hormone since it is released into the blood.

Descartes focused much of his anatomical experimentation on the brain, paying specific attention to the pineal gland – which he argued was the actual “ seat of the soul ”.

In this book, he described the pineal gland and what he believed the function was, and was able to draw the corpus striatum which is made up of the basal ganglia and the internal capsule.

Other mutations of the same gene cause the less severe Rabson-Mendenhall syndrome, in which patients have characteristically abnormal teeth, hypertrophic gingiva ( gums ), and enlargement of the pineal gland.

His expertise involving brain disease led directly to the first successful removal of a brain tumor, which was performed by R. Köhler, and with Fedor Krause ( 1857-1937 ), he reported the first successful removal of a pineal tumor.
