Recently Natasha Mitchell did an excellent two-part All in the Mind podcast about brain plasticity. In part 1 she interviewed Jeffrey Schwartz, MD and Norman Doidge, MD. Dr. Schwartz is the author of The Mind and the Brain: Neuroplasticity and the Power of Mental Force, and Dr. Doidge wrote the recent bestseller,The Brain That Changes Itself: Stories of Personal Triumph from the Frontiers of Brain Science.
In part 2 Mitchell interviews Dr. Doidge further. One of the topics they explore is the "dark side" of plasticity. Since neuroplasticity is a dynamic, competitive process it is actually a factor in how we form our habits, both good and bad . This interview is an excellent follow-up to the interview Dr. Doidge did for the Brain Science Podcast back in Episode 26.
You can listen to the podcasts and get transcripts at the All in the Mind website.
