In this review we address the question of whether selective attentional mechanisms within the ipsilesional field are intact in unilateral lesion patients with spatial neglect and extinction. We consider how a lesion-induced bias in the neural representation of salience critically disrupts the integration of goal-driven and stimulus-driven prioritization signals. This has important consequences for selectivity both within the 'impaired' contralesional field within the 'intact' ipsilesional field. Examples are drawn from the neuropsychological literature and recent experiments conducted within our own laboratory. The implications of ipsilesional spatial selection deficits for rehabilitation are discussed.
在本综述中，我们探讨了患有空间忽视和消退症的单侧脑损伤患者同侧视野内的选择性注意机制是否完好的问题。我们思考了损伤引起的显著性神经表征偏差如何严重破坏目标驱动和刺激驱动的优先级信号的整合。这对“完好”的同侧视野内以及“受损”的对侧视野内的选择性都具有重要影响。文中的例子取自神经心理学文献以及我们自己实验室最近进行的实验。我们还讨论了同侧空间选择缺陷对康复的影响。
