Alcohol is the most widely used psychoactive drug. Exposure to light apparently affects the activity of a small structure in the hypothalamus called the suprachiasmatic nucleus, which sends signals to the nearby pineal gland, whose secretion of the hormone melatonin plays a key role in adjusting biological clocks. We proposed in the mid 1990's that consciousness depends on biologically 'orchestrated' quantum computations in collections of microtubules within The most common, however, is insomnia .
