Functional neural dynamics underlying auditory event-related N1 and N1 suppression response.
Presenting tone triplets of identical stimuli preceded by silent intervals of 30 s produces a series of three N1 averaged event-related potentials (ERPs), the first being of greater amplitude (non-suppressed N1) than the second and third ones (suppressed N1). Maximal statistically independent components (ICs) of single-trial multi-electrode scalp EEG responses to triplets were obtained by ICA a...
متن کاملComparing auditory sustained attention in children with auditory processing disorder and normal children
Introduction: Auditory processing disorder (APD) is a type of abnormal perceptual processing of auditory information within the central auditory nervous system that could be influenced by cognitive factors, such as attention. Attention is one of most important cognitive functions in the development of learning in children, so it is important to recognize and evaluate a variety of attention defi...
متن کاملEffects of brief discrimination-training on the auditory N1 wave.
We determined whether the human N1 evoked by tones with different frequencies might be affected by a brief discrimination-training at one specific frequency. During 1 h training, subjects learned to discriminate a 1062 Hz tone from another tone. Before and after training, subjects heard for 26 min tones with a frequency of 1000 Hz, replaced every sixth one by test tones with frequencies randoml...
متن کاملVisual form predictions facilitate auditory processing at the N1.
Auditory-visual (AV) events often involve a leading visual cue (e.g. auditory-visual speech) that allows the perceiver to generate predictions about the upcoming auditory event. Electrophysiological evidence suggests that when an auditory event is predicted, processing is sped up, i.e., the N1 component of the ERP occurs earlier (N1 facilitation). However, it is not clear (1) whether N1 facilit...
متن کاملModelling auditory attention
Sounds in everyday life seldom appear in isolation. Both humans and machines are constantly flooded with a cacophony of sounds that need to be sorted through and scoured for relevant information-a phenomenon referred to as the 'cocktail party problem'. A key component in parsing acoustic scenes is the role of attention, which mediates perception and behaviour by focusing both sensory and cognit...
