Einstein-Podolsky-Rosen (EPR) correlations between human brains are studied to verify if the brain has a macroscopic quantum component. Pairs of subjects were allowed to interact and were then separated inside semisilent Faraday chambers 14.5 m apart when their EEG activity was registered. Only one subject of each pair was stimulated by 100 flashes. When the stimulated subject showed distinct evoked potentials, the nonstimulated subject showed “transferred potentials” similar to those evoked in the stimulated subject. Control subjects showed no such transferred potentials. The transferred potentials demonstrate brain-to-brain nonlocal EPR correlation between brains, supporting the brain's quantum nature at the macrolevel.
