Abstract
Serotonergic hallucinogens include the prototypical compounds such as mescaline, psilocybin, and LSD, representing the chemical classes of phenethylamines, tryptamines, and ergolines. Known as psychedelics, these compounds induce dramatic alterations of perception, affect, consciousness, and the experience of self. As first discovered in animal studies and recently confirmed in humans, the psychological effects of psychedelics are primarily attributable to the activation of the 5-HT2A subtype of serotonin receptors in brain. Research on psychedelic compounds has provided important insights into the neurobiology of consciousness and naturally occurring psychotic states and may lead to further advances in the development of psychiatric pharmacotherapeutics.
