title: Ambulatory EEG cassette recorders for prolonged electroencephalographic monitoring in animals.
abstract: We describe the use of ambulatory cassette EEG recorders for monitoring in vivo neurophysiologic signals from multiple animals over prolonged periods of time. This technique centers around a simple interface device that attenuates the intracerebral signals to the input range of the recording device and around a common indifferent input for all animals. The resulting analog recordings have the advantage of good signal resolution and rapid review of 24 h of recorded data.
