In my mind this is a non-issue. The brain is constantly processing our environment without us being conciously aware of it. It can absorb, integrate and respond to a stimulus long before we even know it is there.

The pre-cognitive initiating signal to move, eat, speak, etc.. is sent prior to the cognitve recognition of such movement.

We physiological prepare for fight or flight before we actually choose to act. What we perceive as instantaneous is not, but, to me that doesn't imply that there is no free will. Just a lag time between inititation and action.
