注意力是一种机制，我们通过它来选择环境的特定方面进行处理。心理学实验表明，注意力可以被引导到一个空间位置或一个特定的对象。对受过训练的猕猴进行的电生理学研究发现，注意力可以加强皮层V4区神经元的反应。其中一些研究将这些效应归因于空间注意，而另一些研究则认为特征导向注意可能会调节神经元的反应。在这里，我们报告说，神经元相关的空间和功能导向的注意存在于单个神经元在V4区的行为恒河猴。
Attention is the mechanism with which we select specific aspects of our environment for processing. Psychological experiments have shown that attention can be directed to a spatial location or to a particular object. Electrophysiological studies in trained macaque monkeys have found that attention can strengthen the responses of neurons in cortical area V4. Some of these studies have attributed these effects to spatial attention, whereas others have suggested that feature-directed attention may modulate the neuronal response. Here we report that neuronal correlates for both spatial and feature-directed attention exist in individual neurons in area V4 of behaving rhesus monkeys.
