The objective of visual systems neuroscience has shifted over the past few years from determining the receptive fields of cells towards the understanding of higher level cognition in awake animals viewing natural stimuli. In experiments with awake animals it is important to control the relevant aspects of behavior. Most important for vision science is the control of the direction of gaze. Here we present Dual Purkinje eye-tracking on cats, which--as a non-contact method--brings a number of advantages. Along with the presented methods for calibration and for synchronization to off-the-shelf video presentation hardware, this method allows high precision experiments to be performed on cats freely viewing videos of natural scenes.
在过去几年中，视觉系统神经科学的目标已从确定细胞的感受野转向理解清醒动物在观看自然刺激时的高级认知。在对清醒动物进行的实验中，控制行为的相关方面非常重要。对于视觉科学而言，最重要的是控制注视方向。在此，我们展示了用于猫的双浦肯野眼动追踪技术，作为一种非接触式方法，它具有诸多优势。结合所展示的校准方法以及与现成视频呈现硬件同步的方法，该方法能够在猫自由观看自然场景视频时进行高精度实验。
