Reddit reviews Functional Neurology for Practitioners of Manual Medicine

There's a North American functional neurologist named Randy Beck (http://www.ifn.net.au/about-us/) who has a clinic here in Perth, Western Australia.
He's authored a book (http://www.amazon.com/gp/aw/d/0702040622) for manual practinioners. He taught us neurology at Murdoch University in third year and knows his stuff. Something well beyond my understanding but I'd love to get into after Uni.
