Experiment 1a: response conflict performance (correct and incorrect lever presses per minute, ±SEM). (A) Both groups showed accurate acquisition of the conditional discriminations. (B) In extinction, both groups showed accurate performance to the single elements used throughout acquisition. (C) In extinction, both groups showed accurate discrimination performance to congruent stimulus compounds. (D) For incongruent stimulus compounds, retrosplenial cortex lesions (RSC) abolished context-appropriate responding, in contrast to the Sham rats. (Congruent compounds consisted of stimulus elements that elicited the same response during training; incongruent compounds consisted of stimulus elements that elicited different responses during training.)
