【摘要】 提出经硬脑膜对视皮层研究的方法,设计所需的多通道视觉诱发电位实验测试系统。该系统的关键部分为基于LabVIEW软件的视觉刺激器,信号采集系统以及信号处理系统三部分。该测试系统的特点是能够提供多种刺激模式与刺激图形,可以实现多通道数据的同时采集,并可以提供图形化的信号处理界面。经验证该系统能够有效地诱发出可识别的视觉诱发电位,并且可以提取出特征性的视觉诱发电位。更多还原

【Abstract】 This paper proposed a novel research method for studying the visual cortex epidural.A test system for epidural multi-channel visual evoked potential(VEP) recording was designed in our study,which is composed of three important parts,that is,visual stimulator,signal acquisition system and signal processing system.The advantages of this multi-channel visual evoked potential test system were that it provided variety of stimulation models and graphics for stimulation,it could record multi-channel epidural VEP signals simultaneously,and it also provided a graphic interface for signal processing.It verified that this system could induce identifiable VEP effectively and obvious characteristics of VEP could be extracted.更多还原
