设计并构建一套动物脑电-行为同步记录及分析系统,系统主要包括动物行为实验装置、脑电信号与行为图像的同步记录子系统、脑电信号分析和处理子系统.当动物在实验装置中进行特定行为时,同步记录子系统同时记录动物的脑电信号和行为图像,通过分析和处理子系统,提取脑电信号的特征值,为大脑神经活动和行为之间的相关性研究提供实验平台.记录并分析大鼠在进行前肢的“伸-缩”运动时运动皮层的神经元集群活动.实验结果表明,大鼠的初级运动皮层中神经元分布式活动与前肢的动作模式密切相关,通过解读初级运动皮层的神经元集群电信号,可以获得大鼠前肢的运动信息,准确判断和区分前肢不同的动作模式.
Design and construction of a set of animal electroencephalogram - behavior synchronization recording and analysis system, the system includes animal behavior experiment device, EEG and behavioral images of synchronous recording subsystem, EEG signal analysis and processing subsystem.When the animals in the experimental device , The synchronous recording subsystem simultaneously records the EEG and behavior images of the animal and extracts the eigenvalues of the EEG signals by analyzing and processing the sub-system so as to provide an experimental study on the correlation between the neural activity and the behavior of the brain The neuronal clustering activity in the motor cortex of rats during the “stretch-shrink” exercise of forelimbs was recorded and analyzed.Experimental results show that the distribution of neuronal activities in the primary motor cortex of rats is closely related to the forelimb movements By interpreting the electrical signals of the neuronal clusters in the primary motor cortex, the forelimb movement information of the rats can be obtained and different forelimb movements can be accurately judged and distinguished.
