Background: This study explores how threat learning contributes to the development of fear and anxiety. We aim to determine if observed responses indicate a general novelty marker, are solely linked to arousal, and are influenced by valence. Adopting the transdiagnostic RDoC approach, this study focuses on acute and sustained threat within negative valence systems.Aims: Utilizing a modified Threat Conditioning and Extinction Task (TCET), we examined fear memory traces in healthy over three phases (preconditioning, conditioning, extinction). The study involved subjective ratings of faces associ

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
