Electrical and behavioral effects of different types of shock stimuli on the rat.

Abstract

4 commonly used shock sources were studied to evaluate the type of shock most appropriate for use in a typical grid-floor shocking apparatus. The main findings were: the electrical resistance of the rat decreased monotonically from approximately 250 K at the aversion threshold to approximately 5 K at tetanization; the rat's activity varied as a function of the type of shock; constant current shock sources were not suitable at low intensities; in general, constant current sources were felt to be best.
