a, e, i Total intracranial electrodes in the hippocampus, insula, and amygdala, respectively. b, f, j The average local field potentials, represented as median and interquartile range, were significantly linearly correlated with the increasing extracranial currents (all p < 0.05) in hippocampus, insula, and amygdala, respectively. c, g, k Positive correlations of the average local field potentials, expressed as the mean and standard deviation, with the increased stimulation currents were found in hippocampus, insula, and amygdala, respectively (all p < 0.05). d, h, and l The observable variations of local field potentials of the deepest contacts in hippocampus, insula, and amygdala within 180 seconds after the tACS intervention, respectively. All illustrations were standardized based on their raw SEEG signals.
