WebMay 19, 2010 · Purkinje neurons are the output cells of the cerebellar cortex and generate spikes in two distinct modes, known as simple and complex spikes. Revealing the point of origin of these action potentials, and how they conduct into local axon collaterals, is important for understanding local and distal neuronal processing and communication. By … WebOct 11, 2024 · Its main function, however, is to insulate the axon and increase the velocity of action potential propagation. Myelin has properties of low capacitance and high electrical resistance which means it can act as an insulator. Therefore, myelin sheaths insulate axons to increase the speed of electrical signal conduction. WebSchematic of synaptic transmission. An action potential travels down the axon of the presynaptic—sending—cell and arrives at multiple axon terminals branching off from the axon. The axon terminal is adjacent to the dendrite of the postsynaptic—receiving—cell. This spot of close connection between axon and dendrite is the synapse. marine biology themed gifts
