While it may be conventional wisdom that we lose gray matter as we age, neuroscientists and psychologists now understand that our brains keep developing in key areas in middle age. As they do, powerful new systems are created, which allow us to process information faster and cut through complex problems more deftly. Scientists believe we have underestimated the adult brain's potential until now.

For those interested in learning more about these findings and the middle-aged development of the brain, The New York Times presents "Understanding the Middle-Aged Brain," a 60-minute live Webcast featuring New York Times health and medicine editor Barbara Strauch, whose recent book, The Secret Life of the Grown-Up Brain, has struck a chord with adults everywhere who worry about their mental capacity. Following her discussion of the latest developments in this topic, Barbara will then answer questions from students.
