Brain Science Podcast #33: Exercise and the Brain

Episode 33 of the Brain Science Podcast is an interview with Harvard physician, Dr. John Ratey about his new book Spark: The Revolutionary New Science of Exercise and the Brain.

John J Ratey, MD

We explore the exciting evidence about how exercise helps the brain. It stimulates the release of a number of different neurotransmitters and neuropeptides, but probably more importantly it helps keeps these compounds balanced. We consider why exercise is so important in dealing with stress, in treating a wide range of mental illnesses including depression, anxiety, and attention deficit disorder. There is also evidence that exercise improves our ability to learn and our ability to avoid the loss of mental agility associated with aging.

Brain Science Podcast #27: Year-End Review

Episode 27 is a look back on the first 26 episodes of the Brain Science Podcast.

I look back on some of the main topics that we have explored including memory, consciousness, emotions, decision-making, body maps, and plasticity. Then I talk a little about what I hope to do in the covering year.

This episode is a little more personal than most, and will mainly be of interest to regular listeners. It includes some ideas about how you can help the Brain Science Podcast grow and prosper.

However, in preparing this episode I went back over the past year's episodes and I have prepared a list of all the episodes so far and the main topics. This should help both new listeners and regulars to find episodes that pertain to particular topics.

Click here for a brief summary of episode 1-26 with links to the audio files.
