LSD alters dynamic integration and segregation in the human brain.

Neuroimage 2021 02 15;227:117653. Epub 2020 Dec 15.

Division of Anaesthesia, School of Clinical Medicine, University of Cambridge, Cambridge CB2 0QQ, United Kingdom.

Investigating changes in brain function induced by mind-altering substances such as LSD is a powerful method for interrogating and understanding how mind interfaces with brain, by connecting novel psychological phenomena with their neurobiological correlates. LSD is known to increase measures of brain complexity, potentially reflecting a neurobiological correlate of the especially rich phenomenological content of psychedelic-induced experiences. Yet although the subjective stream of consciousness is a constant ebb and flow, no studies to date have investigated how LSD influences the dynamics of functional connectivity in the human brain.

1/f electrophysiological spectra in resting and drug-induced states can be explained by the dynamics of multiple oscillatory relaxation processes.

Neuroimage 2018 10 26;179:582-595. Epub 2018 Jun 26.

Centre for Human Psychopharmacology, School of Health Sciences, Swinburne University of Technology, Melbourne, Australia.

Neurophysiological recordings are dominated by arhythmical activity whose spectra can be characterised by power-law functions, and on this basis are often referred to as reflecting scale-free brain dynamics (1/f). Relatively little is known regarding the neural generators and temporal dynamics of this arhythmical behaviour compared to rhythmical behaviour. Here we used Irregularly Resampled AutoSpectral Analysis (IRASA) to quantify β, in both the high (5-100 Hz, β) and low frequency bands (0. Read More

Increased thalamic resting-state connectivity as a core driver of LSD-induced hallucinations.

Acta Psychiatr Scand 2017 Dec 21;136(6):648-657. Epub 2017 Sep 21.

Department of Psychiatry (UPK), University of Basel, Basel, Switzerland.

Objective: It has been proposed that the thalamocortical system is an important site of action of hallucinogenic drugs and an essential component of the neural correlates of consciousness. Hallucinogenic drugs such as LSD can be used to induce profoundly altered states of consciousness, and it is thus of interest to test the effects of these drugs on this system.

Method: 100 μg LSD was administrated orally to 20 healthy participants prior to fMRI assessment. Read More

Increased Global Functional Connectivity Correlates with LSD-Induced Ego Dissolution.

Curr Biol 2016 04 13;26(8):1043-50. Epub 2016 Apr 13.

Centre for Neuropsychopharmacology, Department of Medicine, Imperial College London, London W12 0NN, UK. Electronic address:

Lysergic acid diethylamide (LSD) is a non-selective serotonin-receptor agonist that was first synthesized in 1938 and identified as (potently) psychoactive in 1943. Psychedelics have been used by indigenous cultures for millennia [1]; however, because of LSD's unique potency and the timing of its discovery (coinciding with a period of major discovery in psychopharmacology), it is generally regarded as the quintessential contemporary psychedelic [2]. LSD has profound modulatory effects on consciousness and was used extensively in psychological research and psychiatric practice in the 1950s and 1960s [3]. Read More

Neural correlates of the LSD experience revealed by multimodal neuroimaging.

Proc Natl Acad Sci U S A 2016 Apr 11;113(17):4853-8. Epub 2016 Apr 11.

Centre for Neuropsychopharmacology, Department of Medicine, Imperial College London, W12 0NN, London, United Kingdom;

Lysergic acid diethylamide (LSD) is the prototypical psychedelic drug, but its effects on the human brain have never been studied before with modern neuroimaging. Here, three complementary neuroimaging techniques: arterial spin labeling (ASL), blood oxygen level-dependent (BOLD) measures, and magnetoencephalography (MEG), implemented during resting state conditions, revealed marked changes in brain activity after LSD that correlated strongly with its characteristic psychological effects. Increased visual cortex cerebral blood flow (CBF), decreased visual cortex alpha power, and a greatly expanded primary visual cortex (V1) functional connectivity profile correlated strongly with ratings of visual hallucinations, implying that intrinsic brain activity exerts greater influence on visual processing in the psychedelic state, thereby defining its hallucinatory quality.
