Hemispheres explained

 A  harvard trained neuroscientist explains her insight into the two sides of the brain as a result of her own stroke experience. I actually found this a little disaffecting to watch, knowing only too well the frustrations suffered by creatives and right-brainers with however-momentarily diminished access to some fairly necessary i.e. socialising left brain functions. But it’s a great illustration of the work that both sides do, and the specific modes of access and engagement that each offers.
