The pineal gland is a cone-shaped gland which is located in the middle of the brains. The gland gets its name from its shape that is similar to that of a pine cone. The pineal gland is five to eight millimeters long and four millimeters wide and weighs only 200 milligrams.
During the juvenile period, the gland has an inhibitory effect on the hormonal action of the gonads. After about the tenth year, together with a reduced effect of the pineal gland, the production of sex hormones can begin.
Through research it has been shown that the gland has a function as a biological clock that controls the daily rhythm and night rhythm. That clock can also get confused with a rapid movement of large distance to the east or west.
Pineal gland and light
Light plays a major role in the pineal gland. If the light namely, by a pulse current from the eyes takes to reach the gland, the production of the hormone melatonin increasing. The pineal gland is itself therefore a converter of light to melatonin.
Creation three substances
Besides the gland makes melatonin also for the production of serotonin and dimethyltryptamine which is related to serotonin. Dimethyltryptamine has psychoactive properties, and could play a role in visual dreams, schizophrenia, and near-death experiences, but the function of the substance is actually up to now still quite unclear.
The pineal gland is often considered the heart of the psychosomatic control. Psychosomatic is that which has to do with the relationship between the psychological and the physical.
As one grows older is likely to calcification of the pineal gland and reduces the production of melatonin causing the reduction of dust is associated with the aging process.
Of negative influence on the gland have, inter alia, stress, certain radiations, and magnetic fields. Also have a large difference in temperature, high altitudes and nutrition deficiency influence.
The biological function of the pineal gland is a long time not been so clear. Although the effect and significance of the gland in recent decades have become clearer, there are still many questions about the function and the overall picture is not yet complete.
Sensitive to noise
Preliminary research has shown that the pineal gland is also sensitive to noise but also there must further be investigated.
