The Eeg of Drowsiness

A historical review of ideas about drowsiness, sleep, and the EEG is followed by a broad-based review of the EEG in drowsiness. Here each EEG pattern is discussed using findings in normal subjects and comparing these to data from the wider EEG literature, allowing for smooth reading and ease of comprehension. More detailed analyses are presented separately for reference use and for comparison and contrast in difficult cases.
