RMTg-lesioned rats remain resistant to the inhibitory effect of footshock on food seeking even when given greater exposure to each shock intensity. (A) A timeline of the extended progressive shock task. (B) RMTg-lesioned rats show a significant increase in the minimum shock intensity required to suppress food seeking by 85% of baseline responding (n=9, 11). (C) Shock breakpoints were negatively correlated with counts of RMTg cells remaining after excitotoxin or saline injections. (D) Analysis of binned data showed that significantly greater shock was required to suppress food seeking in RMTg-lesioned rats. *p<0.05
