Table 3.
Results of the LME model examining the interaction between stimulation frequency (“Stim Freq”) and recording location on normalized EP characteristics: PPa, PPd, and TP. Only interaction effects are reported, with GPi serving as the baseline recording region. NS indicates non-significant results.
