LSD induces profound psychedelic effects, including changes in the meaning of percepts. The subjective effects of LSD are fully blocked by a 5-HT2A receptor antagonist. LSD may alter meaningfulness by increasing activity in cortical regions responsible for processing personal attribution.

BACKGROUND AND OBJECTIVE: Lysergic acid diethylamide (LSD) is used recreationally and in clinical research. The aim of the present study was to characterize the pharmacokinetics and exposure-response relationship of oral LSD. METHODS: We analyzed pharmacokinetic data from two published placebo-controlled, double-blind, cross-over studies using oral administration of LSD 100 and 200 µg in 24 and...

A core aspect of the human self is the attribution of personal relevance to everyday stimuli enabling us to experience our environment as meaningful [1]. However, abnormalities in the attribution of personal relevance to sensory experiences are also critical features of many psychiatric disorders [2, 3]. Despite their clinical relevance, the neurochemical and anatomical substrates enabling...

SUMMARY The prototypical hallucinogen LSD acts via serotonin receptors, and here we describe the crystal structure of LSD in complex with the human serotonin receptor 5-HT2B. The complex reveals conformational rearrangements to accommodate LSD, providing a structural explanation for the conformational selectivity of LSD’s key diethylamide moiety. LSD dissociates exceptionally slowly from both...

Today, there is an increased interest in research on lysergic acid diethylamide (LSD) because it may offer new opportunities in psychotherapy under controlled settings. The more we know about how a drug works in the brain, the more opportunities there will be to exploit it in medicine. Here, based on our previously published papers and investigations, we suggest that LSD-induced visual...

My PhD thesis consisted of two different scientific parts, each supervised by one of my advisors, Prof. Dr. med. Matthias Liechti and Prof. Dr. sc. nat. Katharina Rentsch. One part was to develop liquid chromatography tandem mass spectrometry (LC-MS/MS) methods to measure d-lysergic acid diethylamide (LSD) and its main metabolites in plasma, serum, and urine samples. We established the...

d-Lysergic Acid Diethylamide (LSD) is known for its hallucinogenic properties and psychotic-like symptoms, especially at high doses. It is indeed used as a pharmacological model of psychosis in preclinical research. The goal of this review was to understand the mechanism of action of psychotic-like effects of LSD. We searched Pubmed, Web of Science, Scopus, Google Scholar and articles’...

d-lysergic diethylamide (LSD) is a hallucinogenic drug that interacts with the serotonin (5-HT) system binding to 5-HT1 and 5-HT2 receptors. Little is known about its potential interactions with the dopamine (DA) neurons of the ventral tegmental area (VTA). Using in-vivo electrophysiology in male adult rats, we evaluated the effects of cumulative doses of LSD on VTA DA neuronal activity,...

Mystical-type experiences were infrequent after LSD, possibly because of the set and setting used in the present study. LSD may produce greater or different alterations of consciousness at 200 μg (i.e., a dose that is currently used in psychotherapy in Switzerland) compared with 100 μg (i.e., a dose used in imaging studies). Ego dissolution may reflect plasma levels of LSD, whereas more...

Revisiting the history of postwar LSD (lysergic acid diethylamide) research illuminates how the work of a chemist at the Rockefeller Institute contributed to the development of a biochemical paradigm for mental functioning. Dilworth Wayne Woolley proposed one of the first theories of the biochemistry of mental illness based on empirical evidence. His research with LSD and serotonin had...
