Revision of the Publications Describing the Anatomical Connections and Effects of Lesions and Electrical Stimulation of Brain Structures on the Sleep–Wakefulness Cycle

From the first bioelectric description by Berger (1929), which characterized W as an EEG of fast, low voltage waves (later called activated or desynchronized EEG) and sleep as an EEG of slow, high voltage waves (later called synchronized EEG), experimental researchers have looked for the brain structures responsible for the synchronization or activation of the EEG and conceived of them as sleeping or waking structures, respectively.
