The purpose of this study was to determine whether brain activation triggered by visual stimulus in one subject of a pair of meditators, could be detected in the unstimulated member of the pair when subjects were physically and sensory isolated from each other. Data from this study suggests that some individuals may have the capacity to transfer brain signals under certain conditions, without direct contact.
These subjects were trained in Primordial Sound Meditation (PSM), a mantra-based meditation technique taught at the Chopra Center for Wellbeing, and followed a meditation protocol for 30 days prior to the experimental sessions. Each subject of a pair was placed in separate rooms, while one subject received a visual stimulus, and brain activity was measured in both subjects using standard EEG monitoring.
The EEG results indicated that in some pairs of healthy subjects, a signal can be detected in the brain of a physically isolated member of the pair when the other member is visually stimulated.
There are several studies that seem to validate the hypothesis that, under certain conditions, neural events triggered in one human brain may be transferred to another without direct biological contact. This indicates that humans may connect through signals that are not accounted for in current neurophysiology. Further research is warranted to investigate the nature of the signal, its underlying mechanism, and the states of consciousness conducive to the manifestation of this phenomenon.
