Inactivation effects in choice trials. (A) ROI analysis showing average cue/delay activity in choice trials in control and inactivation sessions. Error bars indicate SEM across trials, *P < 0.05, star color corresponds to the larger condition (statistics presented in SI Appendix, Table S6). (Inset) Predictions of the IHC model. (B) Relative activity difference between ipsi- and contralesional choice trials. Bar amplitudes represent average cue/delay activity difference across sessions (left contralesional choices minus right ipsilesional choices; positive values: left > right; negative values: left < right). Note the increased positive values in several areas, in both hemispheres, following the inactivation (purple > gray), indicating differential enhancement in trials when monkeys choose the contralesional hemifield. Error bars indicate SEM across sessions, *P < 0.05 (statistics presented in SI Appendix, Table S7). (Left and Right Insets) ERA BOLD time-courses from left LIP (Left) and right lTPO (Right) before and after inactivation (see SI Appendix, Fig. S5 for other ROIs). Shaded error bands indicate SEM across trials; blue/orange stars, significant difference between left and right trials in at least one time sample (P < 0.05, sample-wise t test). (Center Inset) Predictions of the IHC model.
