How action potential influences plasticity
WebNeural backpropagation is the phenomenon in which, after the action potential of a neuron creates a voltage spike down the axon (normal propagation), another impulse is generated from the soma and propagates towards the apical portions of the dendritic arbor or dendrites (from which much of the original input current originated). In addition to … WebNeuorplasticity can happen at the synapse, which we can call synaptic neuroplasticity. Synaptic neuroplasticity. Or neuroplasticity can occur at the level of entire cells where the total number of synapses between a neuron and its target cell are changed. This we could call structural neuroplasticity. Structural.

Action potentials open voltage-sensitive calcium channels in excitable cells, leading to an influx of calcium ions. Calcium ions may control, among others, cell excitability, neurotransmitter release, or gene transcription.
