This study sought to investigate the recent claim by H.-O. Karnath and his colleagues that the crucial locus of neurological damage in neglect patients lies in the right superior temporal gyrus (STG), and not in the right posterior parietal cortex (P...

In an earlier paper, we reported task-specific impairments and improvements caused by applying TMS over cortical visual area V5 [Proceedings of the Royal Society of London B 265 (1998) 537]. The phenomenon is further investigated in the present study... Read More about The effect of expectation on facilitation of colour/form conjunction tasks by TMS over area V5.

The right and left visual fields each project to the contralateral cerebral hemispheres. The current study aimed to investigate the extent of the functional overlap of the two hemifields along the vertical meridian. We applied repetitive transcranial...

Complementary localization and lateralization of orienting and motor attention (2001)
Journal Article

It is widely agreed that the right posterior parietal cortex has a preeminent role in visuospatial and orienting attention. A number of lines of evidence suggest that although orienting and the preparation of oculomotor responses are dissociable from...

The role of transcranial magnetic stimulation (TMS) in studies of vision, attention and cognition (2001)

Transcranial magnetic stimulation (TMS) can be conceptualized as a virtual lesion technique, capable of disrupting organized cortical activity, transiently and reversibly. The technique combines good spatial and temporal resolution and, moreover, bec... Read More about The role of transcranial magnetic stimulation (TMS) in studies of vision, attention and cognition.

Visual Field asymmetries in attention and learning (2001)

It has been suggested that attentional resolution is greater in the lower than in the upper visual lfield. As there is no corresponding asymmetry between the areas in the primary visual cortex where the input from upper and lower visual fields is pro...

Our previous studies of the role of the parietal cortex in visual learning and attention showed that the right parietal cortex is required for normal performance on conjunction visual search tasks but that its role depends on whether subjects are nai...

Transcranial magnetic stimulation (TMS) can be used to simulate the effects of highly circumscribed brain damage permanently present in some neuropsychological patients, by reversibly disrupting the normal functioning of the cortical area to which it...

To test a recent suggestion that perceptual learning in visual search is non-specific, two groups of subjects were trained on visual search tasks and tested for transfer of learning to new tasks. One group was trained on parallel (“pop-out”) tasks an... Read More about Perceptual Learning in visual search: some evidence of specificities.
