title: Electrically quiet temperature controller.
abstract: A circuit for an electrically quiet temperature controller is described that is suitable for controlling the temperature of a neurophysiological preparation above ambient temperature. By not generating spurious electrical signals it facilitates the recording of low level biological potential changes when temperature control is required. The device, constructed of standard electronic components, uses a thermistor as a sensing element and an ordinary heat lamp or heating strip as a heating element.
