研究了丘脑枕核损伤对人类反射性定向和选择性注意的影响。在一个空间定向任务中，三名单侧枕损伤的患者确定了一个视觉目标的位置，该目标的位置遵循一个没有信息的线索。病灶靶点的反应比同病灶靶点慢。此外，在长的线索目标间隔患者的反应contralesional目标，出现在以前的线索的位置比非线索的位置，表明枕损害不影响抑制返回的速度。在选择性注意任务中，两名患者确定了一个目标，出现在一个层次的全球-局部层次刺激，而忽略了一个干扰存在于其他水平。干扰物表示与目标相同的反应或不同的反应。在两个视野中的目标的反应时间是相似的干扰效应被忽略的干扰。这些数据表明，从事注意contralesionally不受损的歧视任务和过滤无关的信息不受损contralesionally。
The effects of damage to the pulvinar nucleus of the thalamus in humans on reflexive orienting and selective attention were investigated. In a spatial orienting task three patients with unilateral pulvinar damage determined the location of a visual target that followed a cue that was not informative as to the targets location. Contralesional targets were responded to more slowly than ipsilesional targets. Also, at long cue target intervals patients responses to contralesional targets that appeared at previously cued locations were slower than to non-cued locations indicating that pulvinar damage does not affect inhibition of return. In the selective attention task two of the patients identified a target that appeared at one level of a global-local hierarchical stimulus while ignoring a distractor present at the other level. The distractor indicated either the same response as the target or a different response. Response times to targets in both visual fields were similar as were interference effects from the ignored distractors. These data indicate that engaging attention contralesionally is not impaired in discrimination tasks and that filtering of irrelevant information was not impaired contralesionally.
