Action
Psychedelic drugs act contrastingly according to substance on the processes of various serotonergic receptors, namely the 5-HT group and ligand gated ion channels. This action results in either excited or inhibited levels of cyclic adenosine monophosphate, inositol trisphosphate and diglyceride, neurochemicals responsible for a variety of biological functions. In the psychedelic experience, they effect a drastic cognitive and perceptual alteration and delineation of thought, accompanying all manner of hallucinations.

Famous quotes containing the word action:
“The philosophy of action for action, power for the sake of power, had become an established orthodoxy. “Thou has conquered, O go-getting Babbitt.””
—Aldous Huxley (1894–1963)
“There has never been in history another such culture as the Western civilization M a culture which has practiced the belief that the physical and social environment of man is subject to rational manipulation and that history is subject to the will and action of man; whereas central to the traditional cultures of the rivals of Western civilization, those of Africa and Asia, is a belief that it is environment that dominates man.”
—Ishmael Reed (b. 1938)
“To play is nothing but the imitative substitution of a pleasurable, superfluous and voluntary action for a serious, necessary, imperative and difficult one. At the cradle of play as well as of artistic activity there stood leisure, tedium entailed by increased spiritual mobility, a horror vacui, the need of letting forms no longer imprisoned move freely, of filling empty time with sequences of notes, empty space with sequences of form.”
—Max J. Friedländer (1867–1958)
