This is an extensive overview of the relationship between sleep, neuronal plasticity, and brain function. It reviews the developments and progress being made in the attempt to understand the function of sleep. The audience will be individuals interested in the neurophysiology of the brain and changes related to sleep states. Students, researchers, and clinicians with an interest in the neurobiological aspects of sleep, sleep deprivation, and its effect on cognitive functioning will find the book useful.
