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)
Journal Article
Ellison, A., & Walsh, V. (2001). Visual Field asymmetries in attention and learning. Spatial vision, 14(1), 3-9. https://doi.org/10.1163/156856801741323

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...

The role of the parietal cortex in visual attention - hemispheric asymmetires and the effects of learning: A magnetic stimulation study (1998)
Journal Article
Walsh, V., Ellison, A., Ashbridge, E., & Cowey, A. (1998). The role of the parietal cortex in visual attention - hemispheric asymmetires and the effects of learning: A magnetic stimulation study. Neuropsychologia, 37(2), 245-251. https://doi.org/10.1016/s0028-3932%2898%2900099-2

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...

Task-specific impairments and enhancements induced by magnetic stimulation of human visual area V5 (1998)
Journal Article
Walsh, V., Ellison, A., Battelli, L., & Cowey, A. (1998). Task-specific impairments and enhancements induced by magnetic stimulation of human visual area V5. Proceedings of the Royal Society B: Biological Sciences, 265(1395), 537-543. https://doi.org/10.1098/rspb.1998.0328

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...

Perceptual Learning in visual search: some evidence of specificities (1998)
Journal Article

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.
