Psilocybin asymmetrically modulates outcome-based choice and cortical processing under uncertainty.

bioRxiv : the preprint server for biology August 13, 2026 David S Jacobs, Alejandro Torrado Pacheco, Randall Olson et al. preprint

Emerging clinical research with psilocybin highlights the value of the psychedelic experience on successful treatment of a multitude of psychiatric disorders. While the psychedelic trip or clinical support procedures cannot be modeled in rodents, neural processes critical to meta-learning and flexible modification of previously learned strategies can be quantified during psilocybin exposure....

Decoupling of cortical activity from behavioral state following administration of the classic psychedelic DOI.

Neuropharmacology October 1, 2024 Randall J. Olson, Lowell Bartlett, Alex Sonneborn et al. 3 citations

Administration or consumption of classic psychedelics (CPs) leads to profound changes in experience which are often described as highly novel and meaningful. They have shown substantial promise in treating depressive symptoms and may be therapeutic in other situations. Although research suggests that the therapeutic response is correlated with the intensity of the experience, the neural circuit...

Acute psilocybin enhances cognitive flexibility in rats

Neuropsychopharmacology February 20, 2023 Gabriela Garza, Bita Moghaddam, Alejandro Torrado Pacheco et al. 69 citations

Abstract Psilocybin has been shown to improve symptoms of depression and anxiety when combined with psychotherapy or other clinician-guided interventions. To understand the neural basis for this pattern of clinical efficacy, experimental and conceptual approaches that are different than traditional laboratory models of anxiety and depression are needed. A potential novel mechanism is that acute...
