摘要
针对目前已有大鼠视觉图形刺激系统存在的灵活性差、扩展性弱和成本高等问题,设计并实现了一种新型的视觉图形刺激系统.系统上位机采用VB软件编程产生刺激图形,下位机在刺激图形改变或移动时,向外界输出一个同步脉冲到采集设备.测试结果表明:该系统能很好满足视觉刺激的要求,具有易扩展、成本低等优势,能产生良好的经济社会效益.
In this paper,a new visual graphics stimuli system was designed and implemented to solve the problems of less flexibility,poor extensibility and high which exist in the present visual graphics stimuli systems.VB programming language was applied to develop many kinds of stimulating graphics in the host,while a synchronous pulse to external equipment was produced by the lower controller when the stimulating graphics was altered or shifted.With the advantages of strong extensibility and low cost,the system can adequately satisfy the requirements of visual stimuli.
