Of course, here I must chime in...
The definition of free will you use here implies that 'consciousness' must have the lead, if it is supposed to be genuine free will. But that is a definition that stems from (bad...) Christian theology. Most modern concepts of free will got rid of this inheritance, but obviously neurologists still haven't noticed.
'Free will' means that somebody recognises that he can act according his own reasons, and is not forced to go against them by somebody else
