Psychedelic drugs may exert their effects at intracellular serotonin receptors that serotonin itself, which does not cross cell membranes, cannot reach. The findings were published in the Feb. 17, 2023, issue of Science by researchers from the University of California at Davis.
Psychedelic drugs may exert their effects at intracellular serotonin receptors that serotonin itself, which does not cross cell membranes, cannot reach. The findings were published in the Feb. 17, 2023, issue of Science by researchers from the University of California at Davis.
