Five ways to improve your brainpower

Five ways to improve your brainpower

February 15, 2015

It used to be thought that the brain was hardwired and that, unlike other organs, it could not repair itself or restore lost functions once damaged or diseased. Now we know that, in fact, the brain is neuroplastic – that activity and mental experience can be used to change the structure of the connections within it
