Successfully detected brain wave "When to fly" at bungee jump

byEnrico Strocchi

When a human moves a hand or a finger, the brain has already issued an electrical signal about 0.5 seconds earlier than the moment I intended to move. Cranial nerve activity proving this is "Bereitschaftspotential"In Japanese,"Motion preparation potentialIt is called. Although this movement preparation potential is a phenomenon that has been confirmed only in the laboratory, the latest research has succeeded in measuring the movement preparation potential outside the laboratory for the first time. And, bungee jumping is used to measure exercise preparation potential outside the first laboratory.

Exercise preparation potential is a minute voltage change in the brain, which makes it possible for humans to know what they "intentionally" take. This motion preparation potential was first reported by German researchers in 1964. Since then, a lot of researchers have been working on the study of exercise preparation potential, but the exercise preparation potential is a very weak electrical signal, so far it is accurate to detect in laboratory experiments I was not able to do it.

Exercise preparation potential is a kind of electroencephalogram "Alpha wave"It is an electric signal that is 10 to 100 times faint than one, and it is one of nerve fluctuations detected in brain waves. Because it is only a voltage of a few millionth of a volt and it is very difficult to measure, detection outside the laboratory has not been successful.

However, research teams such as Dr. Surjo R. Soekadar, a neuroscientist at the University of Tubingen in Germany, succeeded in detecting exercise preparation potential outside the laboratory. The method taken by the research team is to use a bungee jump indeed. The experiment was the second highest bungee jumping base in Europe, asked two bungee jumpers to wear a device to detect brain waves and let them fly.

calibrationAfter having had it jump several times for, the research team succeeded in detecting the moment of being conscious of "blown" before the bungee jumpers fly. In other words, it can be said that the subject was able to know beforehand when the subject jumps off the bungee jumping base.

"Experiments show that the boundary of possibilities shifts and neuroscience-related technologies will soon become part of our lives," Soekadar said. Marius Nann, a member of the research team, said, "Since we were able to detect the motion preparation potential with a very small number of jumps, we can see that this electrical signal is well released in bungee jumping" I will.

The result of this research is innovative as a study on the exercise preparation potential, and it has been shown that it is possible to detect the movement preparation potential firmly even outside the laboratory, at least if several conditions are met. This is not only meaningful for future research but also in other research fields and brain computer interface that communicates with human brain and computerBrain machine interfaceThere is a possibility that it may be useful in such as).
