How to increase your mental abilities? Research show that this can be achieved using devices electrical brain stimulation that are freely sold in The internet. Now scientists urge to regulate the gaining the popularity of technology.
It may sound too good to be true, but scientists talk about the great promise of transcranial technology DC stimulation (Transcranial direct current stimulation, TDCS). The method involves exposure to the brain electrical impulses sent through the scalp. it is done to stimulate nerve cells in the brain.
The method is not invasive and is even used by the military to Improving the brain performance of drone pilots.
Exposure to electric current ignites neurons, exerting positive effects on cognitive function not only in healthy people, but also patients with impaired brain function. Previous studies have shown improvement in mathematical abilities in people to whom TDCS therapy has been applied. This effect observed six months after the procedure.
By acting with a weak electric current on the right side of the brain, we we can change the threshold of neurons that transmit information in our brain, and, as a result, improve cognitive functions. Commercial companies became interested in this technology and began to promote it in a circle of gamers, promising them a head start in front of rivals in the game.
One such company advertises an electrode hoop, which help “disperse” the brain, “increasing its performance by 20-40 percent. “Gadget” improves overall well-being and relieves fatigue “- reads an ad citing results research.
Unexpected Results
However, improper use of stimulants may harm health, not benefit. Games and treatments are different things, researchers warn.
One of these devices (shown in the photo below) stimulates brain regions located behind the forehead. They are responsible for Attention.
Brain Stimulator for Gamers

In laboratory conditions, such stimulation lasts no more than 20 minutes at a time. Moreover, to participate in the experiment are allowed only people who have previously undergone rigorous medical inspection.
In the end, devices are applied to the brains of subjects which, according to scientists, can give unexpected results. For example, exposure to other parts of the brain or polarity reversal electrodes can not only not help, but, on the contrary, harm to man.
You can hurt yourself. It is important to know how to use this method, choose the right time and power current, – warn scientists at Oxford University.
Their colleagues at the University of Swansea agree with them. By their brain stimulants can cause cramps and shift mood. An increased risk group includes people under the age of 20 years is the most fruitful period of brain development.
But most of all, the fact that many technically gifted children collect such gadgets with their own hands. On the forum Reddit.com Can Find Burned Skin Complaints head “and” outburst of anger “after brain stimulation by TDCS therapy.

This can happen if the prescribed dosage is exceeded. IN unlike patients, ordinary people to a lesser extent aware of potential risks, says researcher Nick Davis from the University of Swansea.
Marketing is ahead of science
Oxford scientists urge tightened control brain electrical stimulants. Some companies are positioning these gadgets as gaming, although they relate to medical devices appointments subject to appropriate registration and control.
Scientists do not want to ban or restrict access to cognitive enhancement devices. They want to users knew what risks they would have to take in the pursuit of potential benefit.
Another concern is that the technology is not ready yet. for commercial use. According to neurologist Stephen Novel from Yale, companies often pick up from laboratories untested technologies and trying to bring them to market, calling them “sexy.”
Any device with medical functionality should adjusted accordingly. Regulation is the only thing what motivates spending money and time on research, ”says Novel.
According to scientists, interest in technology will only grow. But until additional studies are carried out, they recommend using brain electrical stimulants with caution.
