    Abstract:

    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.
