WebDec 13, 2024 · Input spikes cause the neuron’s membrane potential — the electrical charge across the neuron’s cell wall — to build up. There are also processes that cause this charge to leak; in the absence of input spikes, any built-up membrane potential starts to decay. WebNeuronal action potentials or spikes provide a long-range, noise-resistant means of communication between neurons. As point processes single spikes contain little information in themselves, i.e., outside the context of spikes from other neurons. Moreover, they may fail to cross a synapse.

WebMay 14, 2015 · Bursting is a dynamic state where a neuron repeatedly fires discrete groups or bursts of spikes. Each such burst is followed by a period of quiescence before the next burst occurs. A burst of two spikes is called a doublet, of three spikes is called a triplet, four - quadruplet, etc. Neuronal bursting can play important roles in communication between …
