A dissociation between EEG entropy at slow and fast timescales in non-pharmacological altered states of consciousness

Quick Summary

We examined EEG activity during stroboscopic stimulation and breath-focused meditation/ Brain wave complexity takes a surprising twist during altered states: high-speed signals increase in complexity, as expected, while slower rhythms surprisingly reduce their complexity, adding nuance to our understanding of brain activity and consciousness.
