New Neurons: Good News, Bad News

Posted Apr 25 2008 12:00am

Over the last year we have gladly seen an avalanche of news on adult neurogenesis (the creation of new neurons in adult brains), following recent research reports. Further, we have seen how the news that physical exercise can enhance neurogenesis is becoming common knowledge among many health systems we work with.

Now, the obvious question that doesn’t always get asked is, “What good are new neurons if they don’t survive?”. And that’s where learning, enrichment, mental exercise, are critical.

We are glad to introduce a new Expert Contributor, Dr. Bill Klemm, a professor of Neuroscience at Texas A&M University, who summarizes much research on how new neurons are born-and what they need to live long happy lives.

New Neurons: Good News, Bad News

– By Dr. Bill Klemm 

In the last few years, researchers have discovered that new nerve cells (neurons) are born, presumably from residual stem cells that exist even in adults. That should be good news for all of us as we get older and fear mental decline. The bad news is that these new neurons die, unless our minds are active enough.
