Abstract

Endogenous attention is the cognitive function that selects the relevant pieces of sensory information to achieve goals and it is known to be controlled by dorsal fronto-parietal brain areas. Here we expand this notion by identifying a control attention area located in the temporal lobe. By combining a demanding behavioral paradigm with functional neuroimaging and diffusion tractography, we show that like fronto-parietal attentional areas, the human posterior inferotemporal cortex exhibits significant attentional modulatory activity. This area is functionally distinct from surrounding cortical areas, and is directly connected to parietal and frontal attentional regions. These results show that attentional control spans three cortical lobes and overarches large distances through fiber pathways that run orthogonally to the dominant anterior-posterior axes of sensory processing, thus suggesting a different organizing principle for cognitive control.

摘要

内源性注意是一种认知功能,它选择相关的感觉信息来实现目标,已知它由背侧额顶叶脑区控制。在这里,我们通过确定一个位于颞叶的控制注意区域来扩展这个概念。通过结合一项具有挑战性的行为范式、功能神经影像学和扩散轨迹追踪技术,我们表明,与额顶叶注意区域一样,人类后下颞叶皮层表现出显著的注意调节活动。这个区域在功能上与周围的皮层区域不同,并且与顶叶和额叶的注意区域直接相连。这些结果表明,注意力控制跨越三个皮层叶,并通过与感觉处理的主导前后轴正交的纤维束路径跨越大的距离,从而提示了认知控制的不同组织原则。
