Extended Data Fig. 6: Decoding food likeability rating from high-frequency OFC (top, purple) and (P)HC (bottom, yellow) activity.
From: Four core properties of the human brain valuation system demonstrated in intracranial signals
Left: Time course of decoding accuracy from OFC (top, pooling vmPFC and lOFC) and (P)HC (bottom, pooling hippocampus and PHC) signals. Solid lines represent mean accuracy across 100 testing folds from 225 (and 201) recording sites in the OFC (and (P)HC) in the high frequencies (gamma and high gamma) and dashed lines represent SEM (across tested folds). The accuracy of the classifier was tested against the accuracy of a classifier trained on shuffled ratings (grey line). Stars indicate significant difference (two-sided one-sample t-test, p<0.05, cluster-wise corrected across time points). Right: Regions of interest used in each time course. Red: vmPFC, blue: lOFC, green: hippocampus, brown: PHC.
