Our Brains Don’t Really Rewire, Neuroscientists Caution

Professors Tamar Makin (Cambridge) and John Krakauer (Johns Hopkins) say that when the brain adapts to losses, it uses “latent capacities,” not new ones

We hear a lot about neuroplasticity, — the way the brain compensates for absences or injuries. A recent neuroscience paper offers a look at what the brain is really doing in such cases. One area that has attracted a lot of attention is human echolocation, the ability of a person who is blind — due to damage to the visual cortex of the brain — to use a form of echolocation to sense objects that cannot actually be seen. Professors Tamar Makin (Cambridge) and John Krakauer (Johns Hopkins) propose that what happens in the brain is something like this: In their article, Makin and Krakauer look at a ten seminal studies that purport to show the brain’s ability to reorganise.
