WebApr 10, 2024 · Section snippets Individual dynamics. The HR neuron model [25] is a nonlinear dynamical system composed of 3 differential equations modeling the neuronal activity and aims to study the spike and burst behaviors of the membrane action potential, x (t) written in dimensionless units. A neuron bursting dynamical state is characterized by a … The course of the action potential can be divided into five parts: the rising phase, the peak phase, the falling phase, the undershoot phase, and the refractory period. During the rising phase the membrane potential depolarizes (becomes more positive). The point at which depolarization stops is called the peak phase. At … See more An action potential occurs when the membrane potential of a specific cell location rapidly rises and falls. This depolarization then causes adjacent locations to similarly depolarize. Action potentials occur in … See more Action potentials result from the presence in a cell's membrane of special types of voltage-gated ion channels. A voltage-gated ion channel is a transmembrane protein that has … See more Anatomy of a neuron Several types of cells support an action potential, such as plant cells, muscle cells, and the specialized … See more Chemical synapses In general, action potentials that reach the synaptic knobs cause a neurotransmitter to be released into the … See more Cardiac action potentials The cardiac action potential differs from the neuronal action potential by having an extended plateau, in … See more Nearly all cell membranes in animals, plants and fungi maintain a voltage difference between the exterior and interior of the cell, … See more The action potential generated at the axon hillock propagates as a wave along the axon. The currents flowing inwards at a point on the axon during an action potential spread out along the axon, and depolarize the adjacent sections of its membrane. If … See more
