Effectiveness of Neurofeedback on the Event-Related Potentials in Children with Attention Deficit/Hyperactivity Disorder
Objective: The aim of this study was to investigate the effectiveness of neurofeedback therapy on event-related potential (EPR) at both behavioral and physiological level in children (7-12 years) with Attention Deficit/Hyperactivity Disorder (ADHD). Methods: The current study is a quasi-experimental project whit pre-test and post-test control group. In this study, the subjects (12 patients ...
متن کاملSelective attention to sound location or pitch studied with event-related brain potentials and magnetic fields.
Event-related brain potentials (ERPs) and magnetic fields (ERFs) were used to compare brain activity associated with selective attention to sound location or pitch in humans. Sixteen healthy adults participated in the ERP experiment, and 11 adults in the ERF experiment. In different conditions, the participants focused their attention on a designated sound location or pitch, or pictures present...
متن کاملEvent-related brain potentials during selective attention to depth and form in global stereopsis
To elucidate the discriminating processes of surface depth and boundary form in global stereopsis, event-related brain potentials (ERPs) were investigated by the detection of combinations of the attributes in random sequences. The attentional relevance of depth or form was associated with selection negativities (SNs) over the lateral occipito-temporal regions initiating at about 200 ms post-sti...
متن کاملEvent-related potentials to auditory and visual selective attention in schizophrenia.
BACKGROUND Prior studies have shown a consistent reduction of the auditory P300 in schizophrenia, while the visual attention findings have been mixed. Both the auditory and visual N2b, an earlier, modality-specific attention index, are reduced in schizophrenia, sometimes despite sparing of the visual P300. Thus there may be a dissociation between the N2b and P300 attention effects in auditory a...
متن کاملMechanisms of human attention: event-related potentials and oscillations.
Electrophysiological and hemodynamical responses of the brain allow investigation of the neural origins of human attention. We review attention-related brain responses from auditory and visual tasks employing oddball and novelty paradigms. Dipole localization and intracranial recordings as well as functional magnetic resonance imaging reveal multiple areas involved in generating and modulating ...
