Transcranial brain stimulant has been shown to facilitate everything fromdepressiontoParkinson’s , and a growing consistence of inquiry suggests it could be a massive tool against a potpourri of neurological conditions . Now , unexampled research has suggested that non - invasive transcranial electrical stimulation could boost the memory of older adults for a month , with possible resounding impacts on how health care could plow with age - connect memory decline ( or even boosting your brain ready for an exam ) .

The research , produced by scientists at Boston University , was published inNature Neuroscience .

Building on late study that propose working memory ( short - term storage ) and long - terminal figure memory are controlled by specific areas of the brainiac , the report used dissimilar frequency of electrical stimulation on these areas to see if it improved the several memory types .

The squad raise 150 adult aged 65 and over to complete a project of recalling 20 words while their brain was invariably subjected to transcranial jump current stimulation . High relative frequency were surrender to front of the brainiac in a realm called the dorsolateral prefrontal cortex to target long - term retentivity , while low frequencies were targeted at the inferior parietal lobe in an endeavor to better working memory .

The process was repeat on four straight days . design to test both character of retentivity , the results evaluate how well player could call back items from the start of the tilt ( long - condition remembering ) and from the center of the leaning ( working computer storage ) .

participant show improved retentiveness as the four days progressed , in particular in those that score lowest to set about with . These improved issue could still be measured one calendar month later on , suggesting the therapy has some longer - lasting effects . participant in the control group that receive a placebo stimulation did not better their retentiveness .

“ Their results look very promising , ” says Ines Violante , a neuroscientist at the University of Surrey , in astatement to Nature .

“ They really took advantage of the cumulative knowledge within the playing area . ”

The study is likely unequalled in its methodological analysis , return the stimulant for multiple days in a run-in in contrast to old studies that only did one session . The results have garnered praise from expert in the theatre , though it still remains to be seen how long - lasting the result are as well as what applications the therapy may have .

The squad now hop to dig further into the technology to see whether it could have effects on neurodegenerative disorders .
