A-Z listing (archived)
Psychedelic drugs currently have a circular definition. Classed as hallucinogenic psychoactive drugs which have the primary effect of triggering non-ordinary states of consciousness - termed 'psychedelic' experiences.
Many of the known psychedelic substances have been found to bind-to and activate the brain's serotonin 5-HT2A receptors. ( see: Wikipedia )
Although it has been experimentally found that activating the 5-HT2A receptors leads to a marked increase in spontaneous (glutamate-mediated) synaptic activity in the prefrontal cortex, exactly how and why this leads to 'psychedelic' experiences remains unknown.
