An international collaborative research team led by Professor Kirshbink and Professor Shimojo of the California Institute of Technology, and Associate Professor Maki of the University of Tokyo, gave humans an artificial magnetic stimulus that changed direction, and selectively responded to the change in direction. It was the first time in the world to succeed in capturing a responsive brain wave.
A large number of animals, such as bees, salmon, and migratory birds, use geomagnetism for navigation.You can also train your dog to dig up the buried magnet.However, the magnetic sensitivity of humans was unknown.
In the research, a 3-axis coil was installed in an electromagnetic wave shield dark room, and an experimental device was created to control the magnetic field (intensity changes only in the direction of the geomagnetism) by computer.In addition, even if they are magnetically sensitive, they usually do not come up under the consciousness of manifestation, so the behavioral experiments that give this a problem were temporarily shelved.Then, in order to capture the passive reaction of the brain, brain waves were measured at 64 points on the head surface while magnetically stimulating humans.
As a result, event-related desynchronization of alpha waves (brain waves strongly observed in an idling state without doing anything) was observed in a direction-selective manner.Alpha wave event-related desynchronization is a phenomenon in which the intensity of the alpha wave component (8 to 13 Hz) of the brain wave decreases when an external stimulus (for example, visual or auditory stimulus) is input.This is evidence in response to external stimuli, that is, concrete evidence that humans have subconscious geomagnetic sensitivity.
Not only does this research have heuristic significance, but the experimental method is novel, and it is considered to be one of the guidelines for researchers who are interested in human magnetic sensitivity, consciousness, and sixth sense.In the future, it is expected to develop into behavioral experiments that prove the magnetic sensitivity of humans and research that raises the subconscious to the actual consciousness.
