I have a question that maybe basic and psychological in nature but I'm hoping someone with experience in Neuroscience research or any related fields could answer it. As far as I understand it, there is a common debate as to what influences human decisions and what does not which leads to the concept of 'Free Will', but what I'm curious about is not the influence of human choices but what physiological processes exist that we know, give the human power to choose to begin with and is it similar to motor control processes?

I guess a similar question might be, do we know of any physiological processes that gives an individual control over thinking?
