As someone who has been motivated by chocolate most of my life, I can attest to its incredible powers. Apparently, so can the researchers at NIH where neuroscientists were able to get paralyzed rats to walk again. (http://news.nationalgeographic.com/news/2012/05/120531-paralyzed-rats-walk-science-spinal-cords-health/) The injured rodents, who received chemical injections and electrical stimulation, were later put in little harnesses and began a treadmill regimen. After about six weeks, with the lure of a chocolate reward, they were sprinting up stairs in their harnesses and had a “nearly complete” regrowth of spinal nerve fibers.
While there are many interesting and heuristic aspects to this research far beyond the scope of a chocolate rating website, I can only respect the scientist’s choice of bait, and wonder what other great breakthroughs lie ahead using chocolate as an incentive.
