Neuronal substrates of sensory gating within the human brain

Graded Visual Attention Modulates Brain Responses Evoked by Task-irrelevant Auditory Pitch Changes

The results demonstrate that the brain's response to task-irrelevant sensory changes is strongly influenced by intermodal attentional demands.

High gamma activity in response to deviant auditory stimuli recorded directly from human cortex.

It is suggested that the high gamma oscillations are sensory-induced neocortical ripples, similar in physiological origin to the well-studied ripples of the hippocampus.

Temporal dynamics of selective attention during dichotic listening.

Neuromagnetic source analysis revealed attention-related activity in a cortical network including primary auditory cortices, posterior superior temporal gyrus, planum temporale, and the IPL were prominently involved in stimulus selection, whereas medial frontal regions were linked to initiation of behavioral responses and sustained activity in IFG suggested a role in attentional control.

The Functional Organization of Auditory Working Memory as Revealed by fMRI

The results suggest that auditory spatial and identity dissociations as revealed by functional imaging may be dependent to some degree on the type of processing being carried out.

Age-related changes in processing auditory stimuli during visual attention: evidence for deficits in inhibitory control and sensory memory.

Age-related changes in processing task-irrelevant auditory stimuli are consistent with the inhibitory deficit hypothesis and suggest that impaired inhibitory control of sensory input may play a role in the age-related declines in performance during selective attention tasks.



Neurophysiologic Bases of Speech Discrimination

This work has demonstrated that the MMN provides information about the central processing of fine acoustic differences, the neuroanatomic pathways that encode acoustic change, central auditory processing in the presence of peripheral hearing deficits, and central auditory system plasticity.

Auditory association cortex lesions impair auditory short-term memory in monkeys.

Monkeys that were trained to perform auditory and visual short-term memory tasks (delayed matching-to-sample) received lesions of the auditory association cortex in the superior temporal gyrus, and all monkeys could discriminate sounds closer in frequency than those used in the auditory memory task.

Deviant auditory stimuli activate human left and right auditory cortex differently.

It is suggested that the bilateral MMF components originating in the supratemporal cortex are feature specific whereas the right-hemisphere parietal component reflects more global auditory change detection.

Attention modulates auditory pattern memory as indexed by event-related brain potentials.

The role of selective attention on auditory pattern processing was investigated using the mismatch negativity, an event-related brain potential component associated with sensory memory that modulates auditory pattern memory.

Contribution of human hippocampal region to novelty detection

THE ability to respond to unexpected stimuli (the 'orienting response') is a fundamental characteristic of mammalian behaviour1, but the brain mechanisms by which novelty is detected remain poorly
