A complex systems perspective on psychedelic brain action.

Trends Cogn Sci February 3, 2023 Manesh Girn, Fernando E. Rosas, Richard E. Daws et al. 76 citations

Recent findings suggesting the potential transdiagnostic efficacy of psychedelic-assisted therapy have fostered the need to deepen our understanding of psychedelic brain action. Functional neuroimaging investigations have found that psychedelics reduce the functional segregation of large-scale brain networks. However, beyond this general trend, findings have been largely inconsistent. We argue...

Increased global integration in the brain after psilocybin therapy for depression.

Nat Med April 11, 2022 Richard E. Daws, Christopher Timmermann, Bruna Giribaldi et al. 432 citations

Psilocybin therapy shows antidepressant potential, but its therapeutic actions are not well understood. We assessed the subacute impact of psilocybin on brain function in two clinical trials of depression. The first was an open-label trial of orally administered psilocybin (10 mg and 25 mg, 7 d apart) in patients with treatment-resistant depression. Functional magnetic resonance imaging (fMRI)...

Decreased brain modularity after psilocybin therapy for depression.

Research Square May 20, 2021 Richard E. Daws, Christopher Timmerman, Bruna Giribaldi et al. 11 citations

Abstract Importance Psilocybin therapy shows antidepressant potential; our data link its antidepressant effects to decreased brain network modularity post-treatment. Objective To assess the sub-acute impact of psilocybin on brain activity in patients with depression. Design Pre vs post-treatment resting-state functional MRI (fMRI) was recorded in two trials: 1) Open-label treatment-resistant...

Predicting Responses to Psychedelics: A Prospective Study

Frontiers in Pharmacology November 2, 2018 Adam Hampshire, Christopher Timmermann, Christopher Timmermann et al. 422 citations

Responses to psychedelics are notoriously difficult to predict, yet significant work is currently underway to assess their therapeutic potential and the level of interest in psychedelics among the general public appears to be increasing. We aimed to collect prospective data in order to improve our ability to predict acute- and longer-term responses to psychedelics. Individuals who planned to...
