Human Fields and Their Impact on Brain Waves

During brain function, various groups of neurons fire synchronously. When these groups are very large, the signal amplitude can be high enough to be measured on the surface of the scalp using Electroencephalography (EEG). These electrical waves exhibit certain patterns depending on the brain's activity, whether it is asleep, awake, or performing mental calculations. Additionally, these patterns can be modified by external factors, such as transcranial magnetic stimulation (TMS). TMS involves bringing an antenna that generates variable electromagnetic fields close to specific areas of the skull to treat certain pathologies. Given that the human body naturally generates magnetic fields, a question arises: Can these fields influence the EEG by modulating neuronal function, causing a resonance effect, or through some unknown interaction? This study investigated whether approaching the palm of the hand to the top of the head could induce effects in the EEG. We found that 7 out of 20 subjects exhibited changes in their EEG, specifically an increase in the amplitude of certain frequency bands.
