British students and scientists from the University of York, which is located in Heslington, have found a new way to improve memory. During the experiments, it was found that a person’s ability to remember new information improves if transcranial electrical stimulation is performed during sleep. The test results were published in the scientific journal “Current Biology”, dedicated to problems in various areas of biology.
How was the study conducted?
The biologists set out to find out how the development of memory is related to the waves of brain activity that can be seen using an electroencephalogram (EEG). They are confident that it will be possible to improve the memorization of large amounts of information with the help of modern physiotherapeutic TES therapy.
The technique is non-invasive, the doctor must observe two main principles: the resonant characteristics of the current in relation to endogenous opioid peptides and the direction of the current (from the forehead to the mastoid processes).
A study conducted on volunteers showed the correctness of the statements of scientists. People heard from biologists adjectives and associations close to them. Then all this was repeated during the nap of the volunteers. The electroencephalogram recorded that the subjects saw similar associations during sleep.
As a result of the experiment, it became clear that the explosions of the oscillatory activity of the brain are interconnected with the ability to remember information. The researchers are confident that this discovery will help people who find it difficult to memorize a large number of new words (for example, when learning foreign languages).
Efficiency of transcranial electrical brain stimulation
The methodology was based on research conducted over several years by Professor Lebedev Valery Petrovich at the Institute of Physiology (St. Petersburg). Over the years, therapy has improved, so now it has the following positive results:
- analgesic effect (20-30 times higher than the effectiveness of morphine);
- the psychophysiological status is normalized: depression and stress are relieved, efficiency increases, sleep normalizes, fatigue decreases, mood improves, quality of life increases, symptoms of chronic fatigue decrease;
- healing of damaged tissues is observed;
- the process of autonomic regulation, pressure in the arteries, tone in the vessels is normalized;
- the cellular and humoral immune system is stimulated.
The therapy has a positive effect on the body, as it inhibits the growth of malignant and benign neoplasms, eliminates post-withdrawal affective disorders during advanced alcoholism, and most importantly, the desire to use drugs and alcoholic beverages disappears.
The technique has anti-inflammatory and anti-allergic effects. Transcranial electrical stimulation is recommended for relief of withdrawal symptoms and drug treatment of serious diseases.
Contraindications methods
It is not desirable to conduct physiotherapeutic TES-therapy with:
- hyperthyroidism;
- trauma and brain tumors;
- acute hypertensive crisis;
- epilepsy, convulsions;
- tremors.
If the patient lives with an implanted pacemaker in the body, this procedure is also contraindicated. Do not operate on children under 5 years of age. If the skin is injured in the places where the sensors are attached, therapy is prohibited.
