Abstract
We examined whether extracellular dopamine (DA) increase in medial prefrontal cortex is correlated with the establishment or with the retrieval of an auditory avoidance strategy in a shuttle-box. Using microdialysis from right medial prefrontal cortex (mPFC) in combination with behavioral measures, gerbils were trained on a tone-footshock combination in two sessions on two successive days. Sessions in each animal involving avoidance strategy formation and avoidance strategy retrieval were differentiated post hoc by using the percentage of conditioned responses (CR) and other behavioral measures of training sessions. It was found that exclusively strategy formation correlated with high DA levels in mPFC.
