The average amount of serotonin found in the pineals of normal persons is about 3.52 micrograms per gland. One schizophrenic was found to have a pineal containing 10 micrograms of serotonin, while another patient, a sufferer from delirium tremens, had a pineal containing 22.82 micrograms of serotonin. Owing to the difficulties of obtaining the brains of the recently dead for autopsy, the Giarmin-Freedman sample is pathetically small, consisting only of thirteen cases. The same difficulties which confronted them also confront other workers who might be tempted to confirm these findings on a larger scale.

THERE is a vast literature running back for thousands of years which describes psychedelic experiences, long before 1938, when Albert Hofmann first synthesized d-lysergic acid dyethylamide.
Researchers used to think that eye color was determined by a single gene and followed a simple inheritance pattern in which brown eyes were dominant to blue eyes. Under this model, it was believed that parents who both had blue eyes could not have a child with brown eyes. Although it is uncommon, parents with blue eyes can have children with brown eyes. The inheritance of eye color is more complex than originally suspected because multiple genes are involved. While a child’s eye color can often be predicted by the eye colors of his or her parents and other relatives, genetic variations sometimes produce unexpected results. But try as he would, Lerner could find no connection between melatonin and the pigment cells of mammalian skin.
With aging, the quality of vision worsens due to reasons independent of diseases of the aging eye. While there are many changes of significance in the non-diseased eye, the most functionally important changes seem to be a reduction in pupil size and the loss of accommodation or focusing capability . The area of the pupil governs the amount of light that can reach the retina. The extent to which the pupil dilates decreases with age, leading to a substantial decrease in light received at the retina. In comparison to younger people, it is as though older persons are constantly wearing medium-density sunglasses. Therefore, for any detailed visually guided tasks on which performance varies with illumination, older persons require extra lighting.
The vitreous gel undergoes liquefaction and its opacities — visible as floaters — gradually increase in number. When a creature with binocular vision looks at an object, the eyes must rotate around a vertical axis so that the projection of the image is in the centre of the retina in both eyes. To look at a nearby object, the eyes rotate ‘towards each other’ , while for an object farther away they rotate ‘away from each other’ .
