Abstract：
:Male Fischer 344 rats received either tap water or water containing 250 ppm lead for 90 days prior to training in either Pavlovian fear conditioning or consummatory contrast, an aversive reward reduction paradigm. In Experiment 1, lead-exposed and -unexposed rats were trained in operant chambers over a 6-min session. After 3 min elapsed, three tone-shock pairings were presented over the remainder of the session. Rats then received 7 days of extinction training in an identical procedure with only tones presented, no shocks. Lead-exposed rats exhibited greater behavioral suppression to both the contextual and auditory cues that predicted shock. In Experiment 2, rats were placed in operant chambers daily and allowed to consume either a 15% or a 5% fructose solution for 7 days. On Day 8, the rats consuming the 15% fructose solution were shifted to the 5% solution for 3 days. Lead-exposed rats did not differ from their controls in either initial consumption of either solution or in the suppression of their consumption after shifting to the 5% solution. Taken together, these findings suggest that lead impairs the extinction of fear conditioning and this finding is not due to a nonspecific increase in aversive emotionality.
