The present study aims at identifying the contribution of the 5-HT2A receptor system to the formation of self and personal meaning in normal and altered states of consciousness. Specifically, the effect of the 5-HT2/1/6/7 receptor agonist lysergic acid diethylamide (LSD) on self-consciousness, perception and the making of meaning will be assessed in 25 healthy subjects using a randomized, placebo-controlled, double blind, cross-over design. Furthermore, the contribution of the 5-HT2A receptor to these functions shall be assessed by pretreatment with the specific 5-HT2A antagonist ketanserin.
