Researchers from the UK found that the transcranial magnetic stimulation (TMS) of the prefrontal cerebral cortex makes it possible to improve short-term verbal memory. The article of scientists has been published in the magazine PLOS Biology.
Specialists from Glasgow University together with colleagues from Birmingham and Oxford universities analyzed these studies of 40 students who were asked to remember the lists of words. Half of them did a slow – with a frequency of hertz – a repeated TMS left dorsolateral prefrontal bark. Participants in the control group were obtained by TMS in the scalp area. For verification, scientists repeated the experiment in the same way in relation to 24 students.
It turned out that the words were better remembered by those participants in the experiment that the TMS prefrontal bark was made. The analysis of their electroencephalograms showed that TMS reduced the capacity of beta-waves in the dark area of the brain involved in the processes of perception of information. According to researchers, the repetitive TMS is racmators the parietal area – the activity of which suppresses the prefrontal bark – which leads to an improvement in memory.
