Vaughan Bell takes apart folk neuroscience in the Guardian. My favorite of the misconceptions he takes apart:

Video games, TV violence, porn or any other social spectre of the moment "rewires the brain"
Everything "rewires the brain" as the brain works by making and remaking connections. This is often used in a contradictory fashion to suggest that the brain is both particularly susceptible to change but once changed, can't change back.

As I've said in the past, "neuroplasticity" is not another way of saying "technological determinism." And one of the things I hammer at in my book— which I'm almost done proofing, hooray– is that neruoplasticity means, among other things, that you can get back old abilities that you think have been overgrown by too much time on Facebook or sandblasted by your RSS feed.
