 Jason, the brain treatment that you underwent, did they zap you? What do they do? No, they put sensors on your brain and it's listening. It listens to your brain and then it pumps frequencies back through earphones. So it's completely passive. There's not a therapist dealing with you. There's not somebody manipulating anything or zapping you. It's your brain is listening to itself and it takes a little bit of time and then your brain goes, oh.
