A brain-imaging paper by Kastner and colleagues in 1999 was the first to demonstrate that merely focusing attention at a spatial location changed the baseline activity level in various regions of human visual cortex even before any stimuli appeared. The study provided a touchstone for investigating cognitive-sensory interactions and understanding the proactive endogenous signals that shape perception.
卡斯特纳及其同事在 1999 年发表的一篇脑成像论文首次表明，即使在出现任何刺激之前，仅仅将注意力集中在一个空间位置上，就会改变人类视觉皮层各个区域的基线活动水平。该研究为研究认知-感觉相互作用以及理解塑造感知的主动内源性信号提供了一个基准。
