Event-related potentialAn event-related potential (ERP) is the measured brain response that is the direct result of a specific sensory, cognitive, or motor event. More formally, it is any stereotyped electrophysiological response to a stimulus. The study of the brain in this way provides a noninvasive means of evaluating brain functioning. ERPs are measured by means of electroencephalography (EEG). The magnetoencephalography (MEG) equivalent of ERP is the ERF, or event-related field. Evoked potentials and induced potentials are subtypes of ERPs.
Potentiel évoquéUn potentiel évoqué (PE, dit aussi ERP pour l'anglais Event-Related Potential) désigne la modification du potentiel électrique produite par le système nerveux en réponse à une stimulation externe, notamment sensorielle (un son, une image, etc.) mais aussi à un événement interne, notamment une activité cognitive (attention, préparation motrice, etc.) et enregistré grâce à des techniques comme l'électroencéphalographie (EEG) ou la magnétoencéphalographie (MEG).
Neuroscience of free willNeuroscience of free will, a part of neurophilosophy, is the study of topics related to free will (volition and sense of agency) using neuroscience and the analysis of how findings from such studies may impact the free will debate. As it has become possible to study the living human brain, researchers have begun to observe decision-making processes. Studies have revealed unexpected things about human agency, moral responsibility, and consciousness in general.
