选择性注意对于指导人类行为至关重要。最近的理论将注意力的过程描述为感觉输入之间的有偏见的竞争，但关于这些竞争机制的解剖学基础仍然存在问题。使用经颅磁刺激，我们发现，右顶叶皮层的中断改善了竞争性视觉显示中相关刺激的感知。这种选择性注意力的增强与以前的观察结果是一致的，并建议的上级顶叶小叶和边缘上回在调解视觉输入之间的竞争中发挥着至关重要的作用。(c)2006 Elsevier B.V.保留所有权利。
Selective attention is critical for guiding human behavior. Recent theories have described the process of attention as a biased competition between sensory inputs, but questions remain concerning the anatomical basis of these competitive mechanisms. Using transcranial magnetic stimulation, we found that disruption of the right parietal cortex improved the perception of relevant stimuli in competitive visual displays. This enhancement of selective attention is consistent with previous observations and suggests a crucial role of the superior parietal lobule and supramarginal gyrus in mediating competition between visual inputs.
