Early sensory processing in right hemispheric stroke patients with and without extinction

摘要: While extinction is most commonly viewed as an attentional disorder and not a consequence of failure to process contralesional sensory information, it has been speculated that early processing targets in patients might be fully normal. We used masked visuo-motor response priming paradigm study the influence both ipsilesional peripheral subliminal prime stimuli on central target performance, allowing us compare strength associated with these between right brain damaged without well healthy elderly subjects. found effect informative left visual field performance was significantly reduced extinction. The results suggest low-level deterioration neural representation for general hemispheric damage unrelated presence or absence This suggests spatial bias against information sufficient elicit For occur, this need accompanied by pathological (non-directional) reduction capacity.
