I'm oversimplifying the biology and biochemistry in describing the logic of the science... but not wrong at all wrong re either the facts, the science, or the logic.
You might start by reading a couple of my older posts here...
I've left you a couple of links to something better and more current than some old summary in a wiki...
LOL!!!
Why is it that I'd think a neurologist from an ivy league school might not choose wiki as an first authority in the subject ?
Probably WAY BEYOND most people's ability to discuss intelligently, but they are far from announcing results either way. What they are well prepared to do, is issue some more shares into the market and to their lenders and reverse split to prime us for a new round of PRs. I think pinks have created a lot of experts in THAT field. PumpBoy alerted a lot of people to get in here on some "nice" news yesterday with promises of .018 and the like. That lasted about 80 minutes. Now for the real cause of Alzheimer's, mind numbing boredom.
