there’s plasticity at the other end of the neuron, where axons can sprout offshoots that head off in novel directions. As a spectacular example, when a blind person adept at Braille reads in it, there’s the same activation of the tactile cortex as in anyone else; but amazingly, uniquely, there is also activation of the visual cortex.13 In other words, neurons that normally send axons to the fingertip-processing part of the cortex instead have gone miles off course, growing projections to the visual cortex.
