The purpose of this work is to review recent findings highlighting
the mechanisms and functions of the neuronal oscillations that
structure brain activity across the sleep-wake cycle. An increasing
number of studies conducted in humans and animals, and using a
variety of techniques ranging from intracellular recording to
functional neuroimaging, has provided important insight into the
mechanisms and functional properties of these brain rhythms.
Studies of these rhythms are fundamental not only for basic
neuroscience, but also for clinical neuroscience. At the basic
science level, neuronal oscillations shape the interactions between
different areas of the brain and profoundly impact neural responses
to the environment, thereby mediating the processing of information
in the brain. At the clinical level, brain oscillations are
affected in numerous neurological conditions and might provide
useful biomarkers that inform about patients' evolution and
vulnerability. During sleep, these brain rhythms could provide
functional support to internal states that govern the basic
maintenance of local circuit and systemic interactions. During
wake, the rhythmicity of cortical and subcortical circuits have
been linked with sensory processing, cognitive operations, and
preparation for action. This book will attempt to link together
these sleep and wake functional roles at the level of neuroimaging
and electroencephalographic measures, local field potentials, and
even at the cellular level.
