New study provides insights into the neurophysiological basis of psilocybin-induced alterations in consciousness
“We disproved our initial hypothesis that psychedelic states (here with psilocybin) produce higher complexity,” Ort explained. “Unlike the observed reduction of complexity during dreamless sleep, anesthesia or minimally conscious states, the psychedelic state has the same quantitative complexity as in normal waking – even though the quality of the conscious experience has massively changed.”
Ort and his colleagues found that psilocybin did not significantly alter the PCI (Perturbational Complexity Index) values, indicating that the complexity of the causal interactions within the brain remained stable during the altered states of consciousness induced by psilocybin. However, they did observe increased electroencephalographic signal diversity during restful states after psilocybin administration, suggesting a broader range of brain activity patterns. The findings suggest that while the overall activity of the brain becomes more chaotic during the psychedelic state, the brain’s ability to maintain complex interactions in response to external stimulation is not affected.
