Yes and it is pure bunk. I could get a better reaction from my hamster.
That is NOT even close to being any kind of "proof" of anything. It isn't double blind, has no rigor, it is just random noises.
This is the same as seeing pictures in clouds.
Can't you see she's laughing WITH her father?? She's remembering how she used to tease her mother. She's RESPONDING! That proves she WAS NOT brain dead or in a coma. Did you forget that she's brain-damaged, and won't respond like you or me? That's how they laugh. In case you're not familiar with how brain-damaged people are, THIS is a disabled person RESPONDING. HOW can you say it's bunk??? Please watch it again, very carefully, unless you just don't care or have no interest. If so, there's no reason to respond to you any longer.
