Neurophysiology of Grasping Actions: Evidence from ERPs
We use our hands very frequently to interact with our environment. Neuropsychology together with lesion models and intracranial recordings and imaging work yielded important insights into the functional neuroanatomical correlates of grasping, one important function of our hands, pointing toward a functional parietofrontal brain network. Event-related potentials (ERPs) register directly electric...
متن کاملRunning head: AFFECTIVE EVALUATION OF ACTIONS Erroneous and correct actions have a different affective valence: Evidence from ERPs
The accuracy of actions is swiftly determined through specific monitoring brain systems. Event-related potential (ERP) studies have shown that error commission is associated with the generation of the error-related negativity (ERN/Ne), while correct actions with the correct-related negativity (CRN). Although the exact functional meaning of the ERN/Ne (and CRN) component remains debated, some au...

متن کاملTrust at first sight: evidence from ERPs.
We used event-related potentials (ERPs) to tap the temporal dynamics of first impressions based on face appearance. Participants were asked to evaluate briefly presented faces for trustworthiness and political choice. Behaviorally, participants were better at discriminating faces that were pre-rated as untrustworthy. The ERP results showed that the P100 component was enhanced for untrustworthy ...
متن کاملUnderstanding Manifolds of Grasping Actions
A multitude of grasping taxonomies have been proposed for grasping actions, [1]. Most of them have been designed heuristically and were never compared or evaluated with respect to how effectively they describe the space of natural grasping motions. Furthermore, they are based solely on the final grasp posture of the hand, leaving out of the picture the approach and retreat phases. In the work p...
