With a little assistant , our mentality can be train to cure themselves . After a traumatic nous injury , some of your brain cells go into reset mode , reverting to a shank mobile phone - like province . Using these “ reset cells , ” a mathematical group of German researchers were able to sweet-talk the mentality of hurt mice to regrow nerve cell to supersede damage tissue paper ( the images above are micrographs of the cell regrowing over time ) .
Though their methods are far from unadulterated , this discovery could assist replace all in or damaged brain cells in people lose from Alzheimer ’s as well as any case of injury . It ’s just a thing of protract the brain ’s natural self - healing power .
According to an article in the Proceedings of the National Academies of Science today :
Magdalena Götz and colleague find that cells called astrocyte expand and multiply after brain accidental injury . The authors stimulate brain accidental injury in mice , then observed as quiescent astrocytes activate themselves and became responsive , causing reactive gliosis , which is the universal cellular reaction to brain injury . The investigator found that the reactive astrocyte remained astrocyte in the intellectual pallium , whereas in a electric cell culture they could be sweet-talk to switch to unlike mastermind cell types , include neurons . These results key out astrocyte as a source of stem cells in the trauma site and show that other case of brainiac cells do not have this potential . The authors reason that the cells provide a bright cell type to initiate repair in man after wit harm .
