Hemispheric Asymmetries in Deaf and Hearing During Sustained Peripheral Selective Attention.

Both deaf and hearing participants' selective attention was examined using electroencephalography and a frequency tagging paradigm, and both participant groups showed similar amplifications and reductions in the EEG signal at the attended and unattended frequencies, indicating similar control over their peripheral attention for motion stimuli.

Auditory and somatosensory event-related brain potentials in early blind humans

The present data suggest several compensatory changes in both auditory and somatosensory modalities after the onset of early visual deprivation, which appears to indicate enhanced automatic processing of auditory stimulus changes in the blind.

Visual evoked potentials and event related potentials in congenitally deaf subjects.

Significant reduced amplitudes were found in the occipital area for responses to motion and cognitive stimuli which might be interpreted as a part of functional reorganization of the extrastriate and cognitive cortical areas of deaf subjects.

Visual Attention to the Periphery Is Enhanced in Congenitally Deaf Individuals

Enhanced peripheral attention to moving stimuli in the deaf may be mediated by alterations of the connectivity between MT/MST and the parietal cortex, one of the primary centers for spatial representation and attention.

Changes in Early Cortical Visual Processing Predict Enhanced Reactivity in Deaf Individuals

It is found that deaf subjects were faster than hearing controls at detecting the visual targets, regardless of their location in the visual field (peripheral or peri-foveal), and the results provide the first evidence of a co-variation between modified brain activity and behavioural enhancement in this sensory-deprived population.

Investigating Neural Substrates of Visual Motion Sensitivity in Deaf Individuals

The findings described in this thesis show for the first time that congenital deafness leads to plastic changes within primary visual cortex, and that auditory but not visual motion regions are recruited differentially between deaf and hearing individu- als, depending on the motion type.

Effect of Exogenous Cues on Covert Spatial Orienting in Deaf and Normal Hearing Individuals

The deaf showed a higher cueing effect for the ocular responses than the normal hearing participants, however, there was no group difference for the manual responses, suggesting that the deaf may orient attention faster to targets.

Enhanced reactivity to visual stimuli in deaf individuals.

The findings reveal that enhanced reactivity to visual stimuli in the deaf cannot be explained only by faster orienting of visual attention and can emerge for central as well as peripheral targets.

Altered Cross-Modal Processing in the Primary Auditory Cortex of Congenitally Deaf Adults: A Visual-Somatosensory fMRI Study with a Double-Flash Illusion

The results demonstrate that congenital and profound deafness alters how vision and somatosensation are processed in primary auditory cortex, and cross-modal neuroplasticity in anatomically defined subregions of Heschl's gyrus is examined.
