This an amazing book. Just like the previous book "The Brain that Changes Itself" this one also blew my mind. It's very long book and I think I've lost my interest twice and had to start again from the start few months after. But once i've got beyond the first 30% about Parkinson Disease, I was hooked.
The book talks about how brain stimulation through our sensor could affect it. That includes voice, light and touch. That's probably my favourite part.
Anyway, I've read it over a month ago now and my excitement already dimmed out. That's a great book and I would recommend it to everyone.
