From: Effect of mental fatigue on the central nervous system: an electroencephalography study
Electroencephalographic beta power densities before (open columns) and after(closed columns) 2- (A) and 0-back (B) test sessions and Gaussian distributionsof the power densities on the Pz electrode before (solid line) and after(dotted line) 2-back test session (C). Data are presented as mean and SD.aP < 0.05, significantly different from thecorresponding values before the fatigue-inducing sessions (pairedt-test).
