Group of answer choices always has the same amplitude (amount of depolarization) always has the same duration information is coded through the frequency of action potentials action potentials can sum togeSummarize the steps in generating an action potential as a flowchart. You can make your flowchart on paper and take a picture of it, or make it electronically. Be sure you’ve included: the location in the neuron and components of the neuron involved, the types of cellular transport and ions involved, how action potentials can be stimulated and inhibited. you can get the information from this: https://youtu.be/HYLyhXRp298
