Acute effects of psilocybin on attention and executive functioning in healthy volunteers: a systematic review and multilevel meta-analysis.

Psychopharmacology June 1, 2025 Parsa Yousefi, Morten P. Lietz, Fiachra O'Higgins et al. 7 citations

Psilocybin shows promise for treating neuropsychiatric disorders. However, insight into its acute effects on cognition is lacking. Given the significant role of executive functions in daily life and treatment efficacy, it is crucial to evaluate how psilocybin influences these cognitive domains. This meta-analysis aims to quantify the acute effects of psilocybin on executive functions and...

Psilocybin-assisted neurofeedback for the improvement of executive functions: a randomized semi-naturalistic-lab feasibility study

Philosophical Transactions of the Royal Society B Biological Sciences October 21, 2024 Stefanie Enriquez‐geppert, Jaroslav Krc, Fiachra O'Higgins et al. 5 citations

Executive function deficits, common in psychiatric disorders, hinder daily activities and may be linked to diminished neural plasticity, affecting treatment and training responsiveness. In this pioneering study, we evaluated the feasibility and preliminary efficacy of psilocybin-assisted frontal-midline theta neurofeedback (NF), a neuromodulation technique leveraging neuroplasticity, to improve...
