I shot myself in the WHAT??

A three pound organ that incidentally does not accept bullets as graciously as I had hoped, the brain is part and parcel the most fascinating and intricate  combination of 100 billion neurons yet
neurons are the electrical building blocks of the brain, though they curiously comprise only 10% of brain's matter;  the rest are made of the award-winning glia, long thought to be mere scullery wenches and house servants but now recent research, as Douglas Fields has written about extensively.
Fields has postulated that there is even more research  in terms of new therapies for the brain, especially  brains ravaged by injury and diseases.
