Figure 1. (A) Schematic of the experimental paradigm used in this study. Black boxes indicate the encoding and retrieval epochs. (B) Number of subjects included in each prefrontal and hippocampal region. The colorbar indicates number of subjects, a minimum of 15 subjects and a maximum of 40 subjects contributed to any given unilateral region. (C) Example trace from a single electrode contact depicts the activation onset detection algorithm. The time point of activation (t ) is marked as the time point where the slope is maximized in the 200 msec window centered at the time point where power passes threshold. The t demonstrates that onset of activation does not necessarily coincide with the time that power passes the threshold. (D) Example encoding and retrieval trial show t for three electrodes.
