We review recent evidence for the hemispheric lateralization of attentional systems in the human brain. There is abundant anatomical, neuroimaging, and neuromodulatory evidence for a relative lateralization toward the right hemisphere of some of the cortical networks supporting the attentional systems, especially those including the temporo-parietal junction and the ventro-lateral prefrontal cortex. Damage or disconnection of these right-lateralized nodes may produce severe deficits of spatial and nonspatial attention, as in visual neglect, or of inhibitory control. Finally, we examine the possibility that some of these hemispheric asymmetries are not only exclusive to the human brain, but may also be instrumental in prioritizing information in non-human animals.
我们回顾了近年来关于人类大脑注意力系统半球侧化的证据。有大量的解剖学、神经影像学和神经调节学证据表明，一些支持注意力系统的皮质网络存在相对的右侧化，尤其是包括颞顶联合区和腹外侧前额叶皮层的网络。这些右侧化节点的损伤或断开可能导致严重的空间和非空间注意力缺陷，如视觉忽视，或抑制控制缺陷。最后，我们探讨了这些半球不对称性不仅可能是人类大脑所特有的，而且可能在优先处理非人类动物的信息方面也具有重要作用的可能性。
