Directional Influence between the Human Amygdala and Orbitofrontal Cortex at the Time of Decision-Making
(A) Illustration of a typical single trial of instantaneous frequency in the alpha range and its amplitude derived from the Hilbert-Huang transform of a recorded LFP on the interval −1 to +2 s from stimulus onset. (B, C, D) Instantaneous amplitude averaged over OFC and amygdala contacts conditioned on valence of choice. Colored lines show mean (+/− s.e.). Green horizontal line denotes significant differences at p<.05 FDR corrected.
