In this recent episode of the Brain Science Podcast, Dr. Ginger Campbell speaks with Dr. Penny Lewis about her new book, The Secret World of Sleep: The Surprising Science of the Mind at Rest (2013).
March 18, 2014 / Ginger Campbell, MD
In The Secret World of Sleep: The Surprising Science of the Mind at Rest Dr. Penelope A. Lewis provides a highly readable account of the fascinating world of sleep research. Fascinating research is being carried out with animals as varied as fruit flies and rats, as well as with humans. I was surprised to learn that most people actually find it fairly easy to fall asleep in an fMRI scanner.
I have just posted an interview with Dr. Lewis (BSP 107) that includes a discussion of the role of sleep in memory as well as interesting findings about how synapses in the brain actually change during sleep. We still don't know exactly what sleep (and dreaming) are essential, but research in this field is growing. Dr. Lewis is excited about emerging research that suggests improving slow wave sleep may significantly improve learning and memory.
