Flanker Task-Elicited Event-Related Potential Sources Reflect Human Recombinant Erythropoietin Differential Effects on Parkinson’s Patients

(a) The N2 waveform averaged by groups in the window (200–300 msec) in the electrode site Cz with the highest amplitude. Note that, for the HC group, the early 195 msec latency and for both PD patients a later peak around 224 msec. (b) The N2 component showed maximal activation at middle cingulum and precuneus bilaterally (left located at X = 92, Y = 108, Z = 156). To the right, the localization of the precuneus left. The bicolour scale is showing all the significant values after Bonferroni correction and using permutations.
