http://www.prohealth.com/library/showarticle.cfm?libid=16687 It's a series of three studies done by the same group. This is already showing up on smaller news sources in the context of CFS. I'm a little confused, but I don't think it's a strong argument for a neurological cause of the fatigue. It sounds like the brain tells the muscle to stop working, but the brain bases that decision on information from the muscles. So the muscles could still be the source of the problem?
