人脑每时每刻都要接收大量视觉信息,由于人脑加工信息的能力有限,所以在较大视野内将注意分配给相关信息,同时抑制引起注意分散的不相关信息,对执行目标导向的行为至关重要。这种对视觉信息的选择性和主动性加工以适应当前目标的过程被称作视觉注意(visual attention),且视觉注意可分为自上而下的注意与自下而上的注意两种不同功能。由于来自大脑电信号的神经振荡活动在认知加工中发挥重要作用,已有研究综述了视觉注意与神经振荡(neural oscillation)的密切关系,但并未涉及不同的注意功能与神经振荡的关系。本文系统性调查了不同注意功能与神经振荡的关系,发现额-顶区域的theta频带振荡活动反映了自上而下的认知控制,而后部脑区的theta振荡与自下而上的注意相关。顶-枕区域alpha振荡的偏侧化有助于注意分配,而alpha频带的大规模同步促成了注意对视皮层自上而下的影响。Beta振荡介导了自上而下的信息与自下而上的信息之间的互动,作为信息载体促进了视觉信息处理。Gamma振荡则可能与自上而下和自下而上的注意间整合相关。本文就视觉注意功能与神经振荡关系的研究现状展开综述,旨在揭示不同的神经振荡活动在特定的视觉注意功能中的作用。
The human brain receives a lot of visual information all the time, due to the limited ability of the human brain to process information, it is crucial to allocate attention to relevant information in a larger visual field and suppress irrelevant information that causes attention distraction in order to perform goal-oriented behavior. This process of selective and active processing of visual information to adapt to the current target is called visual attention, visual attention can be divided into two different functions: top-down attention and bottom-up attention. Since neural oscillations from brain electrical signals play an important role in cognitive processing, the close relationship between visual attention and neural oscillations has been reviewed, but the relationship between different attentional functions and neural oscillations has not been discussed. In this paper, we investigated the relationship between different attentional functions and neural oscillations. We found that the theta oscillations in the fronto-parietal region reflected top-down cognitive control, while the theta oscillations in the posterior brain region correlated with bottom-up attention. Lateralization of alpha oscillations in the parietal-occipital region contributes to attention allocation, while large-scale synchronization of alpha oscillations contributes to top-down effects of attention on the visual cortex. Beta oscillations mediate the interaction between top-down information and bottom-up information, and as information carriers promote visual information processing. Gamma oscillations may be related to top-down and bottom-up inter-attention integration. This paper reviews the research status of the relationship between visual attention function and neural oscillations in order to reveal the role of different neural oscillations in specific visual attention function.
