"It is universally believed that just five minutes or more of no blood flow to the brain is always lethal. We had already verified that controlled reflow of blood after a heart attack (adding specific chemical ingredients...) returns healthy cardiac function. We tested if a similar recovery could occur in the brain... and showed an astounding return of complete brain function after 30 minutes of no brain blood flow! ...Yet ...the NIH rejected our request for funding to study this further. They... deemed this... as "not interesting.""
