Poor short-term memory is a fairly common and frequently encountered symptom of brain aging – as we ourselves grow old, our brain gradually experiences some kind of discord between its individual parts. That is why a team of neuroscientists from Boston University decided to contribute to helping older people who want to return at least some of the capabilities of their younger brains by presenting an interesting new method of brain electrostimulation called transcranial brain stimulation, with which they managed to synchronize certain parts of the brain several elderly volunteers who took part in the case.
The study itself was built around the hypothesis that a certain brain stimulation pattern can help older brains to become younger, albeit for a short period of time, thereby improving a person’s short-term working memory. The experiment involved several elderly people aged from 60 to 75 years, each of whom showed positive results after only 25 minutes of the aforementioned electrical stimulation.
Although the real reason for this improvement in the context of experimental neuroscience continues to elude researchers, they nevertheless noticed that their new brain stimulation techniques effectively affect neurons, forcing them to literally synchronize within a single brainwave system — like as a result, after only a short time, all participants in the experiment felt, according to them, greater clarity of thinking, which was also confirmed further by a series of cognitive tests.
Nevertheless, it is worth noting the important fact that some experts are talking about the possible manifestation of the placebo effect here – although the cognitive tests conducted after the experiment, in fact, exclude this possibility. So far, a new type of transcranial stimulation continues to be carefully studied by the developers themselves, but it can already be understood that in the future it has every chance of becoming the basis of a new approach to improving the cognitive capabilities of the elderly brain.
