颞叶皮层在注意控制中的作用

The role of temporal cortex in the control of attention

Hamidreza Ramezanpour, Mazyar Fallah

摘要:

注意力是主动视觉不可或缺的组成部分。与广泛接受的颞叶皮层处理主要集中在被动物体识别的概念相反,最近的一系列研究强调了颞叶皮层结构的作用,特别是上颞沟(STS)和下颞叶(IT)皮层,在引导注意力和执行与行为任务相关的认知程序。这篇理论论文的目标是提出这样一个假设,即颞叶皮层注意网络(TAN)需要必要的组件,以灵活的任务依赖的方式积极参与注意控制。首先,我们将简要讨论颞叶皮层的一般结构,重点是猴子的STS和IT皮层及其对注意力的调节。然后,我们将回顾来自行为和神经生理学研究的证据,这些研究支持他们在认知控制信号存在的情况下指导注意力。接下来,我们提出了一个机制的框架,在颞叶皮层的注意力执行控制。最后,我们总结了颞叶皮层在执行认知程序中的作用,并讨论了它们如何有助于视觉注意的动态性质,以确保灵活的行为。

英文摘要:

Attention is an indispensable component of active vision. Contrary to the widely accepted notion that temporal cortex processing primarily focusses on passive object recognition, a series of very recent studies emphasize the role of temporal cortex structures, specifically the superior temporal sulcus (STS) and inferotemporal (IT) cortex, in guiding attention and implementing cognitive programs relevant for behavioral tasks. The goal of this theoretical paper is to advance the hypothesis that the temporal cortex attention network (TAN) entails necessary components to actively participate in attentional control in a flexible task-dependent manner. First, we will briefly discuss the general architecture of the temporal cortex with a focus on the STS and IT cortex of monkeys and their modulation with attention. Then we will review evidence from behavioral and neurophysiological studies that support their guidance of attention in the presence of cognitive control signals. Next, we propose a mechanistic framework for executive control of attention in the temporal cortex. Finally, we summarize the role of temporal cortex in implementing cognitive programs and discuss how they contribute to the dynamic nature of visual attention to ensure flexible behavior.
