Visual and tactile neglect

TL;DRAbstract

<p>Neglect patients typically fail to report, respond, or orient to information presented in locations further away from the side of the brain lesion. Neglect is most often reported after acute stroke, and is more severe and more frequent after right hemisphere damage.</p><p>This thesis concerns different aspects of the "neglect syndrome" in stroke patients. It was divided into three parts. Study I examined a large sample of patients which performed a line cancellation test where the direction of arm movement and the direction of visual scanning were decoupled. The results support previous findings of a differentiation between perceptual and motor aspects of neglect, and provide further evidence that these components correlate with parietal and frontal brain lesions, respectively.</p><p>In studies II-V, patients performed bisection tasks under different experimental conditions. It was found that performance improved in darkness as compared with performance
