In this tour of sleep and its boundary with wakefulness, internationally renowned sleep scientist David Dinges considers the complex topic of sleepiness. What brain structures are involved in sleep initiation? How does wake state instability impair cognitive activity in the sleepy brain? And what can sleep inertia tell us about why it can be so difficult to get out of bed in the morning?
