Abstract: Performance monitoring represents a critical executive function of the human brain. In an effort to identify its anatomical and physiological aspects, a negative component of event-related potentials (ERPs), which occurs only on incorrect trials,...

Abstract: In a previous study we addressed the question whether a feedback-related negativity (FRN) can be elicited by outcomes that are not contingent on any preceding choice or action (). Participants took part in ...

Abstract: In the present study, a modified version of the Eriksen Flanker Task has been used to study event-related potentials (ERPs) elicited by correct responses, response errors, and invalid negative response feedback following correct button presses (“...

Abstract: We investigated performance monitoring of a group of healthy normal subjects in a delay of gratification paradigm. Focusing on response-locked event-related brain potentials we observed an Ne-Pe-like complex in all conditions. While there was no ...

Abstract: Stop-signal tasks can be used to analyze mechanisms of action control and error monitoring. Previous event-related potential (ERP) studies indicated enhanced stop-signal N2 amplitudes for unsuccessful compared with successful inhibition. The aim ...

Abstract: The discovery of mirror neurons in monkeys has reshaped thinking about how the brain processes observed actions. There is growing evidence that these neurons, which show similar firing patterns for action execution and observation, also exist in ...

Abstract: Objectives: To determine age-related changes in the frequency content, temporal dynamics, and functional reactivity of error-related potentials. Methods: Two groups of subjects, young (mean age 22.5 years) and older (mean age 58.3 years) were ...

Abstract: Obsessive-compulsive disorder (OCD) has been related to a hyperactive frontal-striatal-thalamic circuit and associated with altered mechanisms of action and error monitoring. In the present study, we examined whether these results only hold for ...

Abstract: The present study investigates differences in error processing between Parkinson's disease patients (PD) and controls. More specifically, we wanted to know whether patients with PD showed similar differences in the late error-specific ERP ...

Abstract: Recently, D-amphetamine was shown to increase the error negativity, the so-called “response Ne/ERN,” after incorrect choices of hand. We investigated whether this stimulation of action monitoring would also be present in the monitoring of late ...

Abstract: We conducted a literature review to examine the functional significance of the error positivity (Pe), an error-related electrophysiological brain potential often observed in combination with the error negativity (Ne). The review revealed many ...

Abstract: In between-hand choice reaction time (RT) tasks, the activation of the cerebral motor structures involved in the required response is accompanied by an inhibition of the structures involved in the alternative response. The objectives were (1) to ...
