A way to improve brain function is found

Numerous conversations about improving the brain’s work through stimulation do not abate for a long time. But it seems that a group of scientists from the University of Aalto in Finland and Helsinki University managed to do this. This is written by the magazine Cerebral Cortex .

In a series of experiments, scientists were able to influence metacognitive processes by exciting neurons. This was achieved by the action of magnetic pulses. Such an impact allowed people to more effectively cope with a number of memorization tasks.

It is worth explaining that metacognitive processes are the ability of people to monitor and control various types of memory, attention, emotions, and decision-making. In a number of cases, the so-called Dunning effect – Kruger – occurs when people with low cognitive abilities tend to overestimate their capabilities. They can become a victim of illusion, thinking that they will cope well with certain tasks, although in reality this is not so.

But a simple overestimation of the possibilities is not limited to. Metakognitivnye abilities are violated in a number of diseases, for example, during neurodegenerative processes, which, among other things, negatively affect the tactile memory. So, in patients with Alzheimer’s disease, schizophrenia and brain traumas, the state of health is distorted and the perception of pain, touching cold or hot objects changes.

But back to the experiment: it was attended by 14 volunteers without deviations in the brain. They were scanned with MRI, which allowed to determine the distribution of neural pathways and their relationship to the prefrontal and primary somatosensory cortex, where the tactile signals coming from the sensory organs are processed. It was established that the magnetic stimulation of this area allows a person to better evaluate their effectiveness in performing tasks on tactile memory and even improve the memorization processes. Thus, it is possible not only to improve the functioning of the brain of healthy people, but also to develop methods of therapy for patients with cognitive impairment.
