I have the same question. Definition from Wikipedia "Free will is the capacity of agents to choose between different possible courses of action unimpeded." If your actions and decisions are a result of chemical and electrical activity in your brain, it does still mean that you are in control and unimpeded.

Free will seems to exist in a middle state where you do not think of yourself as a soul separate from your physical form and where you accept yourself as a carbon based organism reacting to processes.

Who is supposed to have this free will?
