| 摘 要： | 微电极导向的立体定向手术中,微电极记录的神经元放电信号噪声干扰严重,信噪比变化大,影响着神经元放电脉冲的分析。利用小波变换和非线性能量算子相结合的一种新的方法能检测出神经元放电。通过对临床不同病人、不同特点的神经元放电信号处理,结果表明:该方法能成功地检测出细胞放电,提取出放电波形。

| Abstract: | The microelectrode recordings of neuron discharge,which contain noises,are very complex and apt to be disturbed by many factors during the microelectrode-guided stereotactic operations.The varying signal-to-noise ratios are obstacles to the analysis of neural spikes.A novel method based on a combination of wavelet-based and non-linear energy operator is presented for the detection of neural spikes.The method is tested for neural signals of different patients and various SNR values.The results demonstrate its performance for successful detection and effective extraction of the waveform of neural spikes. |
