What can we consciously control in our bodies besides our muscles and brain (thought, memory, etc.)? Is the notion Bio Feedback related to this matter?
EDIT: I mean I can move my muscles at will but I can't order my liver to "work" since it's not managed consciously by the human mind. I heard about having some sort of control over temperature, heartbeat, sweating, etc. using techniques like breathing in martial arts or what they teach at the military to fool the lie detector. So my question is : What CAN we control?
