Effects of medial PFC lesions on performance in the rodent gambling task. A) % Advantageous responses. Lesioned rats exhibit a decrease in their choice of advantageous options that progressively worsened across testing. B) % Choice of each hole (H). All rats chose hole 2 (most optimal) more than they chose the other 3 options. Lesioned rats chose hole 3 more frequently than sham-operated rats on post-lesion days 1, 4 and 5 and chose hole 1 less frequently than sham-operated rats on post-lesion day 3. There was no effects of either condition or day of testing on the % Omissions (C), the % Premature responses (D), or the number of magazine entries made (E). *P < 0.05 sham-operated vs lesion; #P < 0.05 lesion compared to baseline; ^P < 0.05 both groups compared to baseline; ‡P < 0.5, sham-operated vs lesion hole 1; †P < 0.05 sham-operated vs lesion hole 3; ∞P < 0.05 hole 2 vs all other holes.
