An Action Potential in a Neuron
更深入的分析(variancen-mean analysis)发现,突触释放概率(pr)减小伴随着释放位点(N)的增多。突触终端(presynaptic bouton)的亚细胞膜片钳(subcellular patch clamp)记录表明,动作电位的半峰宽(action potential half-duration)逐渐减小会导致钙离子通道活性降低,从而导致突触释放概率减小。钙成像数据从侧面验证了这一点。...

However, newer multineuronal recording methods have revealed that ensembles of neurons, rather than individual cells, can form physiological units and generate emergent functional properties and states. As a new paradigm for neuroscience, neural network models have the potential to incorporate knowledge ...

This behaviour is also seen in Aplysia giant neurones and, together with the quantitative effects of varying external ion concentrations, suggests that both sodium and calcium act as carriers of current during the normal action potential.doi:10.1038/215546a0JUNGE...
