Mega Brain

Book excerpt: Scientists have learned more about the brain in the last decade than in all of previous history, and the implications of the latest research are clear: The human brain is far more powerful, and has the potential for immensely greater growth and transformation, than was ever before imagined. These discoveries may constitute the most significant development in learning since the invention of writing. Michael Hutchison captures all the drama, excitement, and adventure as we finally begin to comprehend the most mysterious and complex structure in the universe, the source of human culture, a still untapped reservoir of power and skills. He looks at the recently developed machines and devices that may soon allow us to increase brain size and intelligence; regenerate brain cells; trigger specific brain states such as euphoria, long- and short-term memory, sexual excitement, and creativity; and control the brain's electrical activity in order to alter such "involuntary" mechanisms as blood pressure, heart rate, and the secretion of hormones. Megabrain is a lucid and lively account of where the pioneers in brain research are headed -- and where they are taking us.
