Episode 8: The Neuroscience of Sleep, Memory and Really Good Afternoon Naps

Neuroscience: Amateur Hour

We spend a third of our lives sleeping and there is no greater enjoyment than a really good afternoon nap. Back in preschool, the good old days, naps were built into our daily schedules but as adults - not so much. But should they be? Is there any neurological benefit or detriment to taking a nap?
Tune in to learn a little bit more about the neuroscience behind sleep, memory, and naps!
