Neural Network Spike Detection under Effect of Local Field Potential and Derivative

局部场电位和微分特性影响下神经元网络发放锋电位的检测

There are two difficulties in the spike detection: spike signals are frequently superimposed on local field potential ( LFP) that reflect the activity of populations of cells near the electrode tip, moreover, the recorded extracellular signal represent a time derivative of the intracellular signal.

从记录的信号中检测锋电位（spike）将遇到两个困难：由周期性振荡的局部场电位引起的基线漂移和由溶液-电极-细胞系统的微分效应导致的锋电位波形变化。

After the project supervision department arrives at the field, the professional environment protection engineer shall be equipped and immediately mobilized, who shall formulate the "environment& water protectionsupervision regulations" and actively launch the investigation on local field environment.

监理项目部进驻工作现场后，应配备专业环保监理工程师并及时安排进场，编写“环水保监理细则”，积极开展对当地现场环境的调查工作。
