Serotonergic psychedelics induce distinct patterns of metabolic activity and covariance within biologically informed rat brain networks

Nature Communications August 3, 2026 Frederik Gudmundsen, Julia Czurylo, Daniel Ryskamp Rijsketic et al.

Serotonergic psychedelics show therapeutic potential across neuropsychiatric disorders despite transient acute effects. These compounds share serotonin 2 A receptor agonism but differ in broader pharmacology, motivating a systematic comparison of their neurobiological effects. Here, we use [18 F]FDG-PET in rats to assess acute and one-week effects of psilocybin, LSD, and 2C-B on brain metabolic...

Not all serotonergic psychedelics are alike - they induce distinct patterns of altered metabolic activity and connectivity

May 28, 2024 Frederik Gudmundsen, Julia Czurylo, Camilla Trang Vo et al. 1 citation preprint

Serotonergic psychedelic drugs have shown promising benefits in trials for various neuropsychiatric disorders. While the acute effects of these psychedelics last only a few hours, the positive therapeutic effects can persist long after a single administration. Serotonergic psychedelics produce their psychedelic effects by activating serotonin 2A receptors, but they differ in other...

Psilocybin restrains activity-based anorexia in female rats by enhancing cognitive flexibility: contributions from 5-HT1A and 5-HT2A receptor mechanisms

Molecular Psychiatry April 27, 2024 Kyna Conn, L K Milton, K Huang et al. 44 citations

Abstract Psilocybin has shown promise for alleviating symptoms of depression and is currently in clinical trials for the treatment of anorexia nervosa (AN), a condition that is characterised by persistent cognitive inflexibility. Considering that enhanced cognitive flexibility after psilocybin treatment is reported to occur in individuals with depression, it is plausible that psilocybin could...
