Event-Related Brain Potentials Following Incorrect Feedback in a Time-Estimation Task: Evidence for a Generic Neural System for Error Detection
We examined scalp-recorded event-related potentials following feedback stimuli in a time-estimation task. Six hundred msec after indicating the end of a 1 sec interval, subjects received a visual,Expand

Coherence of gamma-band EEG activity as a basis for associative learning
Different regions of the brain must communicate with each other to provide the basis for the integration of sensory information, sensory-motor coordination and many other functions that are criticalExpand

Effects of constraint-induced movement therapy on patients with chronic motor deficits after stroke: a replication.
BACKGROUND AND PURPOSE Constraint-induced movement therapy (CI therapy) has previously been shown to produce large improvements in actual amount of use of a more affected upper extremity in theExpand

Effect of task conditions on brain responses to threatening faces in social phobics: An event-related functional magnetic resonance imaging study
BACKGROUND The aim of this study was to identify brain activation to socially threatening stimuli in social phobic subjects during different experimental conditions. METHODS With event-relatedExpand

Implementation of error-processing in the human anterior cingulate cortex: a source analysis of the magnetic equivalent of the error-related negativity
Recent research has described a component of human electrical brain activity (the ERN or NE) that is associated with error-processing. In the present experiment, we used magneto-encephalographicExpand

Common and Distinct Brain Activation to Threat and Safety Signals in Social Phobia
Background: Little is known about the functional neuroanatomy underlying the processing of emotional stimuli in social phobia. Objectives: To investigate specific brain activation that is associatedExpand

Event-related brain potentials and affective responses to threat in spider/snake-phobic and non-phobic subjects.
We investigated cortical responses and valence/arousal ratings of spider phobic, snake phobic, and healthy subjects while they were processing feared, fear-relevant, emotional neutral, and pleasantExpand
