What do we mean when we describe a person as intelligent? The concept of intelligence wields a powerful influence on research dealing with the brain and on how individuals progress in society. Yet, remarkably, there is no scientific consensus about the meaning of intelligence. In The Making of Intelligence Ken Richardson looks at how intelligence has been characterized and measured in the past, explores current trends in our understanding and uses of the concept, and predicts what form these trends will take in the future.

He argues that intelligence is not solely predetermined by...

Pain is one of medicine's greatest mysteries. When farmer John Mitson caught his hand in a baler, he cut off his trapped hand and carried it to a neighbor. "Sheer survival and logic" was how he described it. "And strangely, I didn't feel any pain." How can this be? We're taught that pain is a warning message to be heeded at all costs, yet it can switch off in the most agonizing circumstances or switch on for no apparent reason. Many scientists, philosophers, and laypeople imagine pain to operate like a rigid, simple signaling system, as if a particular injury generates a fixed amount of pain...

I think, therefore I am. The legendary pronouncement of philosopher Rene Descartes lingers as accepted wisdom in the Western world nearly four centuries after its author's death. But does thought really come first? Who actually runs the show: we, our thoughts, or the neurons firing within our brains?

Walter J. Freeman explores how we control our behavior and make sense of the world around us. Avoiding determinism both in sociobiology, which proposes that persons' genes control their brains' functioning, and in neuroscience, which posits that their brains' disposition is molded by...

How much of sexual diversity is the result of nature versus nurture? Prevailing theories today lean heavily toward nature. Now a leading researcher in neuroscience and animal behavior shows how, in recent history, scientific claims about sex and gender differences have reflected the culture of the time. Although the conviction that genetics can explain everything is now widespread, the author demonstrates the interaction of culture and environment in the formation of behavioral traits and so provides an important corrective to popular notions of reductionism.

Starting with a summary of...

Igor Aleksander heads a major British team that has applied engineering principles to the understanding of the human brain and has built several pioneering machines, culminating in MAGNUS, which he calls a machine with imagination. When he asks it (in words) to produce an image of a banana that is blue with red spots, the image appears on the screen in seconds.

The idea of such an apparently imaginative, even conscious machine seems heretical and its advocates are often accused of sensationalism, arrogance, or philosophical ignorance. Part of the problem, according to Aleksander, is that...

Why do smokers claim that the first cigarette of the day is the best? What is the biological basis behind some heavy drinkers' belief that the "hair-of-the-dog" method alleviates the effects of a hangover? Why does marijuana seem to affect ones problem-solving capacity? Intoxicating Minds is, in the author's words, "a grand excavation of drug myth." Neither extolling nor condemning drug use, it is a story of scientific and artistic achievement, war and greed, empires and religions, and lessons for the future.

Ciaran Regan looks at each class of drugs, describing the historical...

Most of us remember where we were and what we were doing on September 11, 2001. Why do most experiences leave little trace while some--even terrible ordeals that people wish they could forget--leave memories that last a lifetime? That is the mystery at the heart of this book.

Drawing on fascinating research and case studies, James McGaugh, a distinguished neuroscientist, reveals that the key to understanding how memories are created may well be understanding how they are lost. He shows that lasting memories are not stored instantly. Why the delay? The author explains how the slow...
