Spike action potential

Webaction potential occurred in that axon or neuron. Because action potentials are the units of ... the main spike signal in each of those test data sets. Hint: one MATLAB function that might be especially helpful to you is “find”. Try “help find”. “find” will return the indices of each element in a vector that meets a condition. 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 several types of animal cells, called excitable cells, which include neurons, muscle cells, and in some plant cells. Certain endocrine cells such as pancreatic beta cells, and certain cells of the anterior pituitary gland are also excitable cells.
