Human frontoparietal cortex has long been implicated as a source of attentional control. However, the mechanistic underpinnings of these control functions have remained elusive due to limitations of neuroimaging techniques that rely on anatomical landmarks to localize patterns of activation. The recent advent of topographic mapping via functional magnetic resonance imaging (fMRI) has allowed the reliable parcellation of the network into 18 independent subregions in individual subjects, thereby offering unprecedented opportunities to address a wide range of empirical questions as to how mechanisms of control operate. Here, we review the human neuroimaging literature that has begun to explore space-based, feature-based, object-based and category-based attentional control within the context of topographically defined frontoparietal cortex.
长期以来，人类额顶叶皮质一直被认为是注意力控制的来源。然而，由于依赖解剖学标志来定位激活模式的神经成像技术存在局限性，这些控制功能的机制基础仍然难以捉摸。最近通过功能磁共振成像（fMRI）进行的地形图绘制技术的出现，使得在个体受试者中能够将该网络可靠地划分为18个独立的子区域，从而为解决关于控制机制如何运作的广泛实证问题提供了前所未有的机会。在这里，我们回顾了人类神经成像文献，这些文献已开始在地形学定义的额顶叶皮质背景下探索基于空间、基于特征、基于对象和基于类别的注意力控制。
