I am interested in dynamic vision and motion perception. My previous research has focused on the effects that a brain lesion to the associative visual areas has upon the ability to discriminate and integrate visual events. While this neuropsychological work has suggested a hypothesis about the role of the parietal cortex, the general approach is severely limited. For example, brain lesions caused by a stroke usually extend beyond the area of interest in the study, and a damaged brain may have undergone months or years of reorganization and adopted compensatory strategies. Moreover lesion studies may reveal the capability of other cortical areas in the absence of the damaged cortical tissue and not the true functions of that specific area. For these and other reasons, I am now using the virtual-lesion methodology applying TMS to the visual cortex of healthy volunteers and producing reversible functional disruption. TMS has excellent temporal resolution, and can be spatially confined, and this has been useful in mimicking selective brain lesions.
