This double-blind cross-over brain imaging study (n=22) of psilocybin combined EEG with transcranial magnetic stimulation (TMS) to reveal that psilocybin produces a chaotic pattern of brain activity (versus placebo; LZc complexity under eyes closed). Using TMS, the authors could measure the Perturbational Complexity Index (PCI) due to the stimulation. The difference between psilocybin and placebo on PCI wasn't significant.
