建立猕猴Go/NoGo视觉分辨任务的方法

A Training Program for Visual Discrimination Tasks in Monkeys

摘要: 在认知神经科学研究中，Go/NoGo模型是一种非常有效的研究方法。在本试验中，以两只猕猴为研究对象，采用Go/NoGo模型，以不同的视觉线索作为刺激来研究相关认知行为。结果表明猕猴能够很快学会Go/NoGo视觉分辨任务，而且对NoGo任务的完成要优于对Go任务的完成。本实验建立了一种有效的猕猴Go/NoGo视觉分辨实验的方法及计算机控制系统，为进一步记录神经元活动建立了良好的基础。

Abstract: Go/NoGo tasks are a useful behavioral model in the study of cognitive neurosciences. The present developmental study is aimed at establishing a developmental protocol of Go/NoGo visual-discrimination tasks to investigate more cognitive process. We used two rhesus monkeys to test our procedures. Our results suggested that the monkeys quickly learned Go/NoGo visual-discrimination tasks, and performed NoGo tasks better and easier than Go tasks. Using this visual-discrimination task, we can easily study related cognitive neurosciences.
