Homeostasis enables living organisms to maintain robust functioning by adapting to a changing environment. An instance of homeostatic behavior is the thermoregulation in mammals where a stable internal temperature is kept. In this work we present an electronic realization of a temperature regulation based on a single-effector regulation system. The electronic system contains two thermosensitive neurons, a summation unit processing the spikes and a feedback loop which leads to heating or cooling of the neurons via a Peltier element. The spiking trains of thermosensitive neurons can be processed to stabilize an a priori unknown system-inherent set-point. As important parameters for the set-point the feedback control gain and the activity patterns of the thermosensitive artificial neurons are investigated.
