title: A microprocessor device for the real-time detection of synchronized alpha and spindle activity in the EEG.
abstract: A microprocessor based device is described which permits the real-time detection of synchronized EEG activity within the frequency range of the alpha rhythm or sleep spindles. This device offers a reliable, inexpensive method for EEG analysis according to flexible, user selectable parameters. It can be used either on-line or off-line and provides information as to the occurrence and duration of alpha-spindle EEG activity.
