Plain English Summary
Can one person's brain activity ripple across to someone else sitting in a completely separate, soundproofed room? This study says maybe -- but with a very quiet signal. Six experienced meditators formed 25 sender-receiver pairs. Senders got hit with flashes of light and sound while receivers sat isolated. Standard brain-wave averaging (ERP) found absolutely nothing in the receivers. But a clever new algorithm called GW6, which looks at correlations across brain electrodes, picked up a tiny but statistically significant blip in the receivers' alpha waves -- the rhythm linked to relaxed awareness. We're talking about a 0.5% correlation change, so genuinely tiny. Intriguingly, the receiver response came about 700 milliseconds later, suggesting they weren't reacting to the stimulus itself but tracking the sender's shifted mental state. Major caveats: only six people, they were hand-picked meditators, and the frequency band was chosen after the fact -- all of which means these results need much bigger, pre-registered follow-ups before anyone should get too excited.
Actual Paper Abstract
This study investigated EEG correlates of social interaction at distance between twenty-five pairs of participants who were not connected by any traditional channels of communication. Each session involved the application of 128 stimulations separated by intervals of random duration ranging from 4 to 6 seconds. One of the pair received a one-second stimulation from a light signal produced by an arrangement of red LEDs, and a simultaneous 500 Hz sinusoidal audio signal of the same length. The other member of the pair sat in an isolated sound-proof room, such that any sensory interaction between the pair was impossible. An analysis of the Event-Related Potentials associated with sensory stimulation using traditional averaging methods showed a distinct peak at approximately 300 ms, but only in the EEG activity of subjects who were directly stimulated. However, when a new algorithm was applied to the EEG activity based on the correlation between signals from all active electrodes, a weak but robust response was also detected in the EEG activity of the passive member of the pair, particularly within 9 β 10 Hz in the Alpha range. Using the Bootstrap method and the Monte Carlo emulation, this signal was found to be statistically significant.
Research Notes
Key innovation is the GW6 correlation algorithm, which detects a receiver signal invisible to classical ERP averaging. Builds on the group's 2014 F1000Research confirmatory study (not yet in catalog). Very small N (6 subjects), non-random participant selection, and post-hoc frequency band selection are major caveats. Relevant to the brain-to-brain EEG cluster and the broader telepathy debate.
Investigates whether EEG activity in a sensorily isolated 'receiver' correlates with stimulation experienced by a distant 'sender'. Six meditation-experienced participants formed 25 sender-receiver pairs over three days. Senders received 128 light-and-audio stimulations; receivers sat in separate soundproofed rooms. Traditional ERP averaging found a clear response in senders but nothing in receivers. A novel inter-electrode correlation algorithm (GW6) detected a weak but significant receiver response in the 9-10 Hz alpha band (p = 0.002-0.003, Monte Carlo) and at 8-12 Hz (p = 0.04). Effect was approximately 0.5% correlation change. Receiver latency of ~700 ms suggested tracking of the sender's altered state rather than the stimulus.
