【摘要】 以大鼠作为实验动物,采用近似熵的方法,分析大鼠初级视觉皮层的自发脑电信号,从而判别大鼠安静、睡眠和活动3种状态.实验结果表明,采用近似熵算法,使用较短的数据就能对大鼠的状态进行有效识别,减少了冗余的计算量,解决在复杂隐蔽环境中对大鼠状态的识别问题.更多还原

【Abstract】 With rats as experimental animals,using the approximate entropy method to analyze the spontaneous electroencephalogram(EEG) of the rats in primary visual cortex,thus distinguishing rats’ states which are in quietude,sleep and activity.Experimental results show that using approximate entropy algorithm will be able to identify the state of rats effectively and reduce redundant computation just use the shorter data,as well as to solve the problem of rats’ state identification that hidden in a complex environment.更多还原
