在过去的三十年里，神经科学研究稳步增长，旨在了解大脑中自上而下的注意力调节的功能和来源。这与认识到注意力可能是感官系统的必要组成部分，以支持自然环境中的自然行为有关。复杂性和杂乱性是自然环境中最容易识别的两个特征，它们可以同时包含非常重要和完全无关的刺激。注意力作为一个自适应过滤器，允许每个感官模态优先处理重要刺激的路线，同时抑制对干扰物的反应，从而优化有限的神经资源的使用。换句话说，“注意力”是一系列机制，通过这些机制，生物体能够有效地、有选择地分配有限的神经资源，以实现特定的行为目标。这篇综述为考虑注意框架和现代神经生理学注意研究提供了一些历史背景，重点是视觉注意。沿着考虑了注意力和眼跳规划之间的特定关系，提供了一种常见的注意力效应和神经机制的分类。我们检验了注意的前运动理论的有效性，该理论认为注意和眼跳规划是一回事。虽然有强有力的证据表明注意力和眼动规划是相似的，具有共同的神经基质，但也有证据表明这两种功能并不同义。最后，我们研究神经生理学的解释功能障碍的注意缺陷多动障碍（ADHD）和自闭症谱系障碍（ASD）的社会损害的假设，部分归因于注意力控制回路的扰动。
The last three decades has seen a steady growth of neuroscience research aimed at understanding the functions and sources of top-down attentional modulation in the brain. This correlates with recognition that attention may be a necessary component of sensory systems to support natural behaviors in natural environments. Complexity and clutter are two of the most recognizable hallmarks of natural environments, which can simultaneously contain vitally important and completely irrelevant stimuli. Attention serves as an adaptive filter allowing each sensory modality preferential processing routes for important stimuli while suppressing responses to distracters, thus optimizing use of limited neural resources. In other words, “attention” is the family of mechanisms by which organisms are able to effectively and selectively allocate limited neural resources to achieve specific behavioral goals. This review provides some historical context for considering attentional frameworks and modern neurophysiological attention research, focusing on visual attention. A taxonomy of common attentional effects and neural mechanisms is provided, along with consideration of the specific relationship between attention and saccade planning. We examine the validity of premotor theories of attention, which posit that attention and saccade planning are one and the same. While there is strong evidence that attention and oculomotor planning are similar, with shared neural substrates, there is also evidence that these two functions are not synonymous. Finally, we examine neurophysiological explanations for dysfunction in Attention Deficit Hyperactivity Disorder (ADHD) and the hypothesis that social impairment in Autism Spectrum Disorders (ASD) is partially attributable to perturbations of attentional control circuitry.
