Fig. 9: High gamma activity in the amygdala codes novelty.
From: Reward recalibrates rule representations in human amygdala and hippocampus intracranial recordings
A High gamma activity in the amygdala in the decision phase in the first block (early/ novel) relative to the last block (late/ familiar) after a stimulus set change (black lines represent mean and shaded regions represents standard error and condition (see legend)). Vertical dashed line at t = 0 corresponds to choice stimulus onset time. The horizontal black line at the top of the plot represents the time intervals of significant clusters (permutation test, p = .0024, FWEC, two-tailed). B Mean difference in activity between conditions across patients within significant time points shown in A ordered by size of effect. Horizontal dashed line is the mean difference across all patients. AMY Amygdala. Source data are provided as a Source Data file.
