I am currently reading the excellent Who’s in Charge?: Free Will and the Science of the Brain which delves into the nature of consciousness and free will. Like all good cross over science books it can be read by the lay person without much difficulty.
Whilst follow up on a chapter on split brain surgery I came across this nifty little piece .
The interesting thing about neuroscience is the drift it has into philosophy and the nature of free will. This cross pollination comes courtesy of new imagining technology that somewhat disturbingly shows that the body begins to take action before a conscious thought has begun. People are not as in charge as they believe they might be.
