The interaction effect in TP for each subject.

<p>(A) The conjunction map that combined the true-color versus false-color contrast with the interaction effect between Period (first half versus second half of sessions) and True-False for each of the 3 subjects (M1 to M3) at <i>p</i> < 0.01. Each slice’s anterior/posterior position is indicated on the top left corner (mm relative to the interaural canal). (B–D) FMRI responses to true- and false-colored objects in TP from the first and second halves of sessions for each subject, respectively. Individual analyses demonstrated similar trends for the 3 monkeys, although the results were not significant, likely due to the limited sample size used as a result of the request to avoid double dipping and the impact of the learning effect. (E–G) fMRI responses to true- and false-colored objects in TP for each session in each subject. Bars display mean values +/− SEM. Red asterisks indicate a significant difference between responses evoked by true- and false-colored stimuli; *<i>p</i> < 0.05, **<i>p</i> < 0.01, ***<i>p</i> < 0.001.
