Stroke is a violation of blood circulation in the brain, which usually leads to disability. In 2023, there were about 420 thousand patients in Russia. Only 10-15% is completely restored and about 20% of the first month die. The chance of healing depends on different factors, including brain activity.
Scientists examine the electrical signals (preparation potentials) in the brain that appear before the movement. During the experiments, the participants pressed the button after the bulb signal – both healthy and affected hand. Even if the patient could not fully print, he was asked to try – and this has already activated the necessary areas of the brain.
Modern healing methods are also used. For example, the brain cooling helps to increase the level of consciousness and anesthesia with xenone stimulates the formation of new neural connections.
Research helps to deeper how the brain reacts to movement and gives hope to more accurate and effective rehabilitation after a stroke.
