On Wednesday, in what many experts are calling a milestone in neuroscience, researchers published a spectacular new map of the brain, detailing nearly 100 previously unknown regions — an unprecedented glimpse into the machinery of the human mind.

While an important advance, the new atlas is hardly the final word on the brain’s workings. It may take decades for scientists to figure out what each region is doing, and more will be discovered in coming decades.

“This map you should think of as version 1.0,” said Matthew F. Glasser, a neuroscientist at Washington University School of Medicine and lead author of the new research. “There may be a version 2.0 as the data get better and more eyes look at the data. We hope the map can evolve as the science progresses.”

Ad Hominem is the most familiar of informal fallacies, and—with the possible exception of Undistributed Middle—the most familiar logical fallacy of them all.

For instance, the charge of "ad hominem" is often raised during American political campaigns, but is seldom logically warranted. We vote for, elect, and are governed by politicians, not platforms; in fact, political platforms are primarily symbolic and seldom enacted. So, personal criticisms are logically relevant to deciding who to vote for. Of course, such criticisms may be logically relevant but factually mistaken, or wrong in some other non-logical way.

Dr. Eben Alexander III had dismissed near-death revelations of God and heaven as explainable by the hard wiring of the human brain.

“During my coma my brain wasn’t working improperly,” he writes in his book. “It wasn’t working at all.”

“My entire neocortex — the outer surface of the brain, the part that makes us human — was entirely shut down, inoperative,” he said.
