以往研究发现，疼痛诱发的gamma频段高频振荡信号（gamma band oscillations，GBO）是最能客观反映疼痛程度的特异性生物指标之一(Hu &Iannetti, 2019; Peng et al., 2018)。然而，GBO的神经起源一直以来存在较大争议：有些研究提示，GBO可能来源于初级躯体感觉皮层（primary somatosensory cortex，S1）(Peng et al., 2018; Zhang et al., 2012)，而另一些研究则支持GBO起源于初级运动皮层（primary motor cortex，M1）(Schulz et al., 2012)。值得注意的是，这些研究多借助脑电技术研究GBO的特性，但脑电空间分辨率低，难以明确GBO的脑内神经电生理活动基础。
由PST开发的、兼容E-Prime 3.0的EyeLink插件已经开始发售。该工具包允许用户使用E-Prime图形编程对象来设计和编制EyeLink实验程序，包含E-Prime与EyeLink连接所需的所有功能。
More and more people are publishing eye-tracking research in open-access journals. This is due, in large part, to the increased number of open-access journals as well as greater interest in publishing research that anyone can use and view without paying for access. For ease and convenience, there …
Only a generation ago, eye tracking typically required complex and expensive equipment and considerable technical expertise on the part of the researcher. Analyzing eye movement data was often a slow and laborious process. As such, it is perhaps unsurprising that it was a relative niche field. …
What is eye tracking? Put simply, eye tracking is the process of measuring eye movements. A typical goal for eye tracking research is to establish where people look (i.e., their “point of regard” or “gaze\\\\\\\"). To this end, scientists usually use a video-based eye tracker, such as the EyeLink 1000 …
