Yes, there really is a brain that destroys itself. And it's a brain just like the one in your head. But not every one of the brains like yours will ultimately destroy itself. However, if the destroying begins, then the signs of this are described in what neurologists take to be the symptoms of "neurodegenerative diseases. Those most often encountered are Alzheimer's and Parkinson's disease, but there are many others-surprisingly many, as explained here. This is the first ever evolutionary explanation of these diseases, which sheds new light on their origin, basic nature, previously...
