Rebuttal to Steven Novella's Body Snatchers, Phantom Limbs, and Alien Hands

Dr. Steven Novella says that we cannot trust are own experiences, well of course we can't unless of course their is strong collaboration by highly credential scientists, as well as evidence to support it. Steven Novella then goes us to say that brain activity is sufficient cause to explain consciousness how so?. Simply saying so, is not going to do. Many neuroscientists have also lump into this false assumption perhaps brain activity strongly correlates with consciousness but isn't the sole cause of consciousness.
