An international mega-analysis of psychedelic drug effects on brain circuit function

Nature Medicine April 1, 2026 Manesh Girn, Manoj K. Doss, Leor Roseman et al. 8 citations

Psychedelic drugs are re-emerging as promising scientific and clinical tools. However, despite a rapidly expanding literature on their therapeutic value, the neural mechanisms underlying psychedelic effects remain unclear. Resting-state functional magnetic resonance imaging studies of acute psychedelic effects, conducted independently by several research groups, have so far yielded fragmented...

The emotional architecture of the psychedelic brain

Trends in Cognitive Sciences August 18, 2025 Flora Moujaes, Nathalie M. Rieser, L. Belinger et al. 5 citations

Serotonergic psychedelics are being explored as treatments for a range of psychiatric conditions. Promising results in mood disorders indicate that their effects on emotional processing may play a central role in their therapeutic potential. However, mechanistic and clinical studies paint a complex picture of the impact of psychedelics on emotions and mood. Here, we review recent findings on...

Ketamine Alters Tuning of Neural and Behavioral Spatial Working Memory Precision

bioRxiv Preprint Server February 10, 2025 Masih Rahmati, Flora Moujaes, Nina Purg Suljič et al. 1 citation preprint

Deficits in working memory (WM) are a hallmark of neuropsy-chiatric disorders such as schizophrenia, yet their neurobiological basis remains poorly understood. Glutamate N-methyl-D-aspartate receptors (NMDARs) are critical for spatial WM (sWM), with NMDAR antagonist ketamine known to attenuate task-evoked activation and reduce sWM accuracy. Cortical microcircuit models hypothesize that NMDAR...

Ketamine induces multiple individually distinct whole-brain functional connectivity signatures.

Elife April 17, 2024 Flora Moujaes, Jie Lisa Ji, Masih Rahmati et al. 23 citations

Ketamine has emerged as one of the most promising therapies for treatment-resistant depression. However, inter-individual variability in response to ketamine is still not well understood and it is unclear how ketamine's molecular mechanisms connect to its neural and behavioral effects. We conducted a single-blind placebo-controlled study, with participants blinded to their treatment condition....

Psilocybin-induced changes in cerebral blood flow are associated with acute and baseline inter-individual differences.

Scientific Reports October 14, 2023 Nathalie M. Rieser, Ladina P Gubser, Flora Moujaes et al. 14 citations

Research into the use of psilocybin for the treatment of psychiatric disorders is a growing field. Nevertheless, robust brain-behavior relationships linking psilocybin-induced brain changes to subjective drug-induced effects have not been established. Furthermore, it is unclear if the acute neural effects are dependent on individual heterogeneity in baseline characteristics. To address this, we...

Comparing Neural Correlates of Consciousness: From Psychedelics to Hypnosis and Meditation

Biological Psychiatry Cognitive Neuroscience and Neuroimaging July 17, 2023 Flora Moujaes, Nathalie M. Rieser, Christophe Phillips et al. 19 citations

BACKGROUND: Pharmacological and nonpharmacological methods of inducing altered states of consciousness (ASCs) are becoming increasingly relevant in the treatment of psychiatric disorders. While comparisons between them are often drawn, to date no study has directly compared their neural correlates. METHODS: To address this knowledge gap, we directly compared 2 pharmacological methods...

Toward Mapping Neurobehavioral Heterogeneity of Psychedelic Neurobiology in Humans

Biological Psychiatry December 7, 2022 Flora Moujaes, Katrin H. Preller, Jie Lisa Ji et al. 44 citations

Precision psychiatry aims to identify markers of interindividual variability that allow for predicting the right treatment for each patient. However, bridging the gap between molecular-level manipulations and neural systems-level functional alterations remains an unsolved problem in psychiatry. After decades of low success rates in pharmaceutical research and development for psychiatric drugs,...
