Topic: sustained cognitive load

Perceptual decision-making involves interpreting external stimuli and selecting the most appropriate response. Success depends on cognitive control, which includes processes like attention, working-memory, and inhibitory control regulated by differential responses of fronto-parietal networks. However, the effects on behavior and neural activity of mental fatigue induced by sustained cognitive control are still unclear. Here we show that sustained cognitive load alters cortical dynamics, leading to faster, automatic responses and hence to an increased error rate. We acquired continuous hd-EEG d
