Attention-dependent sound offset-related brain potentials

Selective 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...

Mechanisms of Visuospatial Attention: Evidence from Event-related Brain Potentials

A series of experiments are reviewed that studied mechanisms underlying visuospatial attention by measuring the influence of attentional selectivity on event-related brain potentials (ERPs). The results are interpreted within a theoretical frameworkdeveloped by LaBerge(1995) and LaBerge andBrown(1989). Spatial attention can have an effect on occipital P1 and N1 components in trial-by-trial cuei...

Microsaccade-related brain potentials signal the focus of visuospatial attention

Covert shifts of visuospatial attention are traditionally assumed to occur in the absence of oculomotor behavior. In contrast, recent behavioral studies have linked attentional cueing effects to the occurrence of microsaccades, small eye movements executed involuntarily during attempted fixation. Here we used a new type of electrophysiological marker to explore the attention-microsaccade relati...

Mapping Speech Sound to Mental Representation: Neurophonological Evidence from Event-Related Brain Potentials

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 ...
