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.

EEG activity in monopolar derivations 01 and 02 was recorded in pairs of subjects while they remained inside two semisilent Faraday chambers, separated by aproximately 14.5 meters. One of the subjects of each pair was stimulated by 100 flashes while the other subject received no stimulus. Averages of the electrophysiological activity, synchronized with the stimuli, were obtained in both subjects before and after they had interacted. When the stimulated subject showed distinct evoked potentials, the non-stimulated subject showed none before interaction, but did show potentials similar to those evoked in the stimulated subject after interacting. These potentials we call Transferred Potentials. When the stimulated subject showed no distinct evoked potentials, the transferred potentials were absent in the non stimulated subject both before and after they interacted. Various control situations were conducted without the subject's knowledge. In one of the control experiments, random samples of brain activity without stimulation were taken and averaged. In others, stimuli were applied to an empty chamber with a subject located in the other chamber. In both cases, transferred potentials were not found. This shows that these potentials depend upon previous interaction and upon the evoked potential's conspicuous appearance, and shows that the Transferred Potentials are the result of a specific brain-to-brain relationship.

Electrophysiological evidence is presented showing an interaction between brain activity of human subjects during direct communication, an interaction which occurs when subjects are able to feel each other's presence without the use of any sensory stimuli. Subjects who had previously established direct communication were asked to sit in complete darkness in two different electromagnetically insulated chambers. One of the subjects was stimulated and it was found that the potential thus evoked could be transferred to the nonstimulated subject. These findings support the postulates of the Syntergic Theory. 1
