When a woman’s silent hemisphere was shown a picture of a pin-up girl she giggled. She blamed it on their ‘funny machine’. When another woman’s silent hemisphere was shown a video of a man being pushed into a fire, she said, ‘I don’t really know why, but I’m kind of scared. I feel jumpy. I think maybe I don’t like this room. Or maybe it’s you. You’re making me nervous. I know I like Dr Gazzaniga, but, right now, I’m scared of him.’
