Abstract Background Serotonergic psychedelics show promise for treating psychiatric disorders, with symptom improvements lasting for weeks after a single dose. Clarifying the neural basis of these effects would benefit from an identification of empirical biomarkers of such lasting shifts in brain function. Resting state EEG offers a rapid (<5 minute), low-cost window into functional brain...
Abstract Serotonergic psychedelics (e.g., psilocybin) have shown potential for treating psychiatric disorders, with therapeutic effects lasting weeks after a single dose. Predictive processing theories posit that psychedelics work by loosening priors or high-level beliefs, including ingrained biases that have become pathological, leading to shifts in bottom-up vs top-down information processing...
