title: Measurement of diurnal core temperatures of rats in operant cages by AM telemetry.
abstract: A special AM telemetric system of recording core temperature was developed for rats working in individual, adjacent operant conditioning chambers within a sound-attenuated room. The system monitored core temperatures of each rat continuously and recorded them, in degrees Celsius, every 30 min so that diurnal patterns and fluctuations after saline or drug injections could be determined. Periodic comparisons showed close agreement with temperatures recorded by a rectal probe.
