Post-stimulus Endogenous and Exogenous Oscillations Are Differentially Modulated by Task Difficulty

Post-stimulus Endogenous and Exogenous Oscillations Are Differentially Modulated by Task Difficulty

We investigate the modulation of post-stimulus endogenous and exogenous oscillations when a perceptual decision is made more difficult. We use exogenous frequency tagging to induce steady-state visual evoked potentials (SSVEP) while subjects perform a face-car discrimination task, the difficulty of...
