a real gun in my hand so is it anything like reality either from them from what we know of course the mechanics are somewhat different but it seems the brain responds in exactly the same way for a simulation and a real situation is that it is a. uncurious so i'll take off anything metallic that are inserted like yours is from it set up over here. to find out what happens in my head when i shoot i take an m.r.i. scan. with a joystick in my hand and a screen above me i have to shoot as many opponents as possible. klaus observes how my brain reacts. and indeed every time i hit an opponent the reward system is activated at the same time the part of the brain responsible for empathy is switched off.
