Fig. 1: Behavioral and neural activation characteristics of VFT in PD-NC and PD-EL subtype.

A PD-EL demonstrates a significant decrease in the number of generated words compared to PD-NC. B Cortical activity during VFT in PD-NC. C Cortical activity during VFT in PD-EL. D This panel shows the comparison between B and C, specifically indicating that reduced activity is observed in regions including DLPFC, VLPFC, SMA, left OFC, left IPL, and mPFC during VFT in PD-EL (C) patients compared to PD-NC (B). Error bars indicate standard deviation (s.d.). **p < 0.01. All brain activation results are significant at p < 0.05, FDR corrected.
