Effects of IL cortex inactivations on the rCET. (A) Baclofen/muscimol (BacMus) inactivation of the IL decreased choice of HR for all animals (inactivation: F1,20 = 6.111, P = 0.023). (B) However, IL inactivation had no significant effect on animals' accuracy (inactivation/inactivation × group/choice × inactivation/choice × inactivation × group: all Fs < 1.338, NS). (C) IL inactivation also significantly increased premature responding for all animals across both trial types (inactivation: F1,20 = 6.766, P = 0.017; inactivation × group/choice × inactivation/choice × inactivation × group/group: all Fs < 2.570, NS). (D) Inactivation of the IL increased nosepoke-response omissions for all animals across both trial types, indicating difficulties remaining engaged with the trial (inactivation: F1,20 = 19.041, P < 0.001; inactivation × group/choice × inactivation/choice × inactivation × group: all Fs < 1.380, NS). Data shown are the mean percent for each variable (±SEM).
