    Here you’ll examine the ways addiction alters the brain by numbing the pleasure center, sensitizing the dopamine system, and inhibiting the prefrontal cortex. Combined, these altered brain functions lead to strong cravings and a reduced ability to control one’s actions. This foray into neuroscience will forever change the way you think about addiction.

    One of the most complicated and advanced computers on Earth can't be purchased in any store. This astonishing device, responsible for storing and retrieving vast quantities of information that can be accessed at a moment's notice, is the human brain. How does such a dynamic and powerful machine make memories, learn a language, and remember how to drive a car? What habits can we adopt in order to learn more effectively throughout our lives? The answers to these questions are merely the tip of the iceberg in The Learning Brain.

    The Addictive Brain is a fair and balanced investigation of addiction, backed by hard science and behavioral science. Most of us have probably seen the old antidrug commercial in which an actor compares your brain on drugs to an egg sizzling in a hot frying pan. That's a powerful image, but it doesn't tell us what actually happens when drugs enter your body and interact with neurochemical processes.

    We're all getting older every day, and scientific research has shown that starting in our 20s, some brain functions begin a linear decline. But is old age all doom and gloom? Not at all! While it's true that some functions in the aging brain decline, neuroscientists have discovered that many other brain functions remain stable - or even improve - as we age.
