Previous thinking: Memories are stored by locked-in neural connections.
Present: The brain can add neurons,  to establish new memories.
New neurons seem able to migrate, suggesting that therapeutic cells can be guided to areas damaged by disease or injury.

Midlife in the United States - A national study of Health and Wellbeing.


The main purpose of MIDUS is to collect in-depth, long-term information from a national sample of Americans about the many factors, such as work and family life, daily stressors, psychological outlooks, social relationships, and community, that influence their health (mental and physical) as they age. More recently, MIDUS is also assessing numerous biological and neurological factors that are part of explaining why some Americans remain healthy and vital as they grow older, while others do not.

"Over the past 20 years, we scientists have shown – in one brain area after another and in system after system – that the brain is actually highly adaptive (or plastic) in adults and remains so throughout life.” Dr Michael Merzenich. Read Michael's blog - On the Brain.
