Found a way to improve brain function

Numerous conversations about improving brain function by stimulating not cease for a long time. But it seems that a group of scientists from the University of Aalto in Finland, and the University of Helsinki managed to do it. This writes the magazine Cerebral Cortex.

Found a way to improve brain function

In a series of experiments, the researchers were able to affect the metacognition through the excitation of neurons. It turned out to carry out the action of the magnetic pulses. Such exposure has allowed people to cope more effectively with a number of tasks on memorization.

We should clarify that metacognition refers to the ability of people to monitor and control various types of memory, attention, emotions and decision-making. In some cases, a so-called effect Dunning - Kruger when people with low cognitive abilities tend to overestimate their capabilities. They can become the victim of an illusion, thinking that they coped well with certain tasks, although in reality it is not.

But a simple revaluation of possibilities is not limited. Metacognitive abilities are violated in a number of diseases, for example, in the course of neurodegenerative processes which, among other things, adversely affect the tactile memory. Thus, patients with Alzheimer's disease, schizophrenia and cerebral trauma being distorted and changed the perception of pain, touching the hot or cold objects. But back to the experiment: it was attended by 14 volunteers with no abnormalities in the brain. They are scanned by MRI, which allowed to determine the distribution of neural pathways and their connection to the prefrontal and primary somatosensory cortex, where the processing of the incoming signals tactile senses. It was found that magnetic stimulation of this area allows a person to better assess its effectiveness in carrying out the tasks to tactile memory, and even improve the memorization process. Thus it is possible not only to improve the brain function of healthy people, but also to develop therapies for patients with cognitive impairment.
