一、微电极实验系统生物电信号如:心电、脑电、肌电神经电位等目前已成为临床诊断和生理、药理研究的重要指标和依据.从微观来看,所有这些生物电信号都来源于细胞电位的总和.对细胞兴奋性的深入研究促进了细胞生理学、微量药理学以及相应的微电极实验技术的迅速发展,使某些领域为之面貌一新,许多难解之谜得到了较好的解释. First, the microelectrode experimental system Bioelectric signals such as: ECG, EEG, myoelectric nerve potential has now become an important indicator of clinical diagnosis and physiology, pharmacology and evidence from the microscopic point of view, all of these bioelectric signals are source In the sum of cell potentials.A thorough study of cell excitability has promoted the rapid development of cell physiology, micro-pharmacology and corresponding microelectrode experimental techniques, made some areas look new and many mysteries have been more than Good explanation.
