In this hour of Iowa Public Radio’s River to River, Dr Eric Dyken talks with host Ben Kieffer about various sleep studies, and takes listener questions.

“That part of the brain, the hippocampus, is where you take new memories and you prepare them for permanent storage. And many researchers believe that that new memory, the bad one we’ve had after the big argument we’ve had with one of our family members, is right there in the hippocampus, and then if you settle a little bit of sleep, you’ll encode it throughout the rest of the cortex, throughout the rest of the brain, in a more permanent fashion.”
