Wheel running produces conditioned food aversion

Previous investigations of conditioned taste aversion (CTA) induced by wheel running have used flavored liquids such as conditioned stimuli (CSs). Assuming that classical conditioning mediates activity anorexia, it is expected that CTA induced by physical activity should extend to food stimuli. The...

Description
Summary:Previous investigations of conditioned taste aversion (CTA) induced by wheel running have used flavored liquids such as conditioned stimuli (CSs). Assuming that classical conditioning mediates activity anorexia, it is expected that CTA induced by physical activity should extend to food stimuli. The main purpose of the present experiment was to investigate this possibility. Rats were given a 60-min access to a running wheel [unconditioned stimulus (US)] either before or after being exposed to a novel distinctive flavored food (CS). An additional group had access to running wheels 4 h after receiving the CS food. Results from the present experiment indicate that regimented and contingent periods of wheel running decrease consumption of a food available before wheel running in nondeprived rats.
