In what way is a neuron like a miniature decision-making device?

Question

Quizplus · Accepted Answer

Neurons make decisions in the form of whether or not to fire an action potential or impulse down the axon. This decision is based on the summation of incoming signals and whether they exceed a certain threshold. Therefore, a neuron can be thought of as a miniature decision-making device, deciding whether or not to transmit information to other neurons. Choices A and B are also functions of a neuron, but they do not necessarily involve a decision-making process as they are more automatic functions of a neuron. Choice D is not accurate as the speed of an impulse traveling down the axon is determined by the size and myelination of the axon, not a decision made by the neuron.
