From: Effect of mental fatigue on the central nervous system: an electroencephalography study
Electroencephalographic alpha 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 P3 (C) and O2 (D) electrodes before (solid lines)and after (dotted lines) 2-back test session. Data are presented as meanand SD. aP < 0.05, significantly different from thecorresponding values before the fatigue-inducing sessions (pairedt-test).
