LIFE: A NEW SERIES Miracles and mysteries on a tantalizing scientific frontier.

THE BRAIN OCTOBER 1・1971・50¢

PART I Man strains the powers of his mind to explore that amazing master of his body

It is the most highly organized bit of matter in the universe, this three-pound, electrochemical double handful of cells that thrives on change, allows us to move, see and think, to cre-ate, to love and be conscious of our actions. Since man first became aware of its existence, he has struggled to comprehend its miracles and miseries, punching crude holes in the bones that protect it and arbitrarily assigning moral and intellectual values to the lumps and bumps on its outer surface. His goals then and now have been the same: to gain a true understanding of how the brain works and use this knowledge not only to treat disease, but to improve the very quality of life. Today thousands of scientists from dozens of disciplines are pursuing these goals in the ultimate assault on man's last great scientific frontier on earth. Yet there are difficulties-and dangers. After a decade of intense study many basic questions remain unanswered. In fact, it is possible that the brain may be governed by principles too complex for it to grasp. And even if man does learn to dismantle the loom that spins out his existence, he will find himself with knowledge that could be misused. This five-part series will discuss the brain's basic cell, the neuron; pathways for emotion, awareness and intelligence; what happens when brain biochemistry goes wrong or drugs abuse it; and the roots of our behavior. Here, in a remarkable sequence of pictures by Swedish photographer Lennart Nilsson, the series begins with a tour through the brain and the system of nerves that serves it.
