Synchronized Brain Oscillations and Their Disruption by Ascending Brainstem Reticular Influxes

The physiological bases of the principal EEG synchronized rhythms are summarized here because these rhythms are used to identify objectively waking and sleep states. Most of their alterations are induced by increased or decreased activity in brainstem neurons with thalamic, basal forebrain, hippocampal, and neocortical projections. The knowledge of cellular mechanisms underlying the synchronization of EEG waves is therefore necessary to understand the role played by brainstem modulatory systems.
