Three year old Chase Britton was born completely missing his cerebellum - the part of the brain that controls motor skills, balance and emotions - and his pons - the part of the brain stem that controls such basic functions as breathing
. It seems like he shouldn't be able to sit up or crawl, but he's learning to walk!
Doctors say 'He has the MRI of a vegetable'. His older brother says 'He acts like a normal kid'.http://www.aolnews.com/2011/02/12/chase-britton-boy-without-a-cerebellum-baffles-doctors/
