Fig 7. Activation maps according to the level of difficulty.

Fig 7

Units are in μmol.l −1. Both high and low load conditions elicit bilateral DLPFC activities. The high load minus low load subtraction map (High—Low) shows significantly greater activation of the right DLPFC. Activations shown 14 s post-stimulus onset. p < 0.001. fNIRSOFT® software (www.biopac.com/fNIR-Software-Professional-Edition) was used to produce this figure.
