Considering ethics now before radically new brain technologies get away from us

Imagine infusing thousands of wireless devices into your brain, and using them to both monitor its activity and directly influence its actions. It sounds like the stuff of science fiction, and for the moment it still is – but possibly not for long. Brain research is on a roll at the moment. And as it converges with advances in science and technology more broadly, it's transforming what we are likely to be able to achieve in the near future. Spurring the field on is the promise of more effective treatments for debilitating neurological and psychological disorders such as epilepsy, Parkinson's disease and depression.
