The human brain is an amazing organ. It is in charge of all our physical

functions, and it is the source of all our emotions and thoughts. All human

creations—our art, our architecture, our technologies—begin with the brain.

Our brains, in fact, are what make us essentially human. The unique abilities

of the human brain are what most clearly separate us from apes, and it is our

brain, not brawn, that has established our predominate role on the planet. Our

physical bodies, while amazing in their own right, are relatively weak. We have

no fangs or talons, and even the most developed human musculature pales

compared to that of a grizzly or an ox. Nevertheless, we thrive as no other

animal has thrived on this planet. Why? Because the brain has allowed us to

control and adapt the environment to suit our needs, delivering us from many of

the harsher realities of nature.
