Figure 7.

The amygdala, but not the BF, exhibits a trial-by-trial correlation between firing rate and reaction time. A, Average correlation coefficients for amygdala sites with negative spatial selectivity (i.e., spatial selectivity index < 0.5; left) and positive spatial selectivity (i.e., spatial selectivity index > 0.5; right) for reward-contra (cyan) and reward-ipsi trials (magenta); x values are the mean strength of spatial selectivity (|ROC–0.5|) for each of the three groups. B, Same as A for BF sites. C, D, Same as A and B except that the data are from reward-absent trials (comparing contralateral and ipsilateral saccades). E, Data for the significant comparison (box in A) split by activity type and monkey. Green asterisks indicate significant comparison (t test, p < 0.05) and crosses indicate trend effects (p < 0.1).
