Gene Cohen presents the findings of the latest research on the brain and aging:
♦ The brain is continually resculpting itself in response to experience and learning.
• New brain cells do form throughout life.
The brain's emotional circuitry matures and becomes more balanced with age.
• The brain's-two hemispheres are more equally used by older adults.
Much of the decline in mental abilities formerly associated with aging is not caused by aging per se but by specific diseases such as Alzheimer's or mental illnesses such as depression. Healthy older brains are often as good as or better than younger brains in a wide variety of tasks.
