Quizplus · Accepted Answer

The diagram shows the process of positive feedback, whereby the influx of positively charged ions (mainly sodium) leads to the depolarization of the neuron, which in turn opens more ion channels and causes more influx of positive ions, ultimately resulting in the generation of an action potential.
