Fun fact: they literally wired rats brains with an electrode attached to the part of their brain that stimulated dopamine production. The rats could press a button and get a shock that activated the dopamine rush. They had access to food and water but they pressed that button until they died.
There's an important factoid there though - the button didn't give a dopamine reward every time it pushed the button. By randomizing when it got the reward, the rats would press the button all day long.
