MOREOVER A single neuron usually has one axon, which expands off from a part of the cell body. This I called the axon hillock(#h k). The axon main purpose is to conduct electrical signals generated at the axon hillock down its length. These signals are called action potentials(动作电位). e The other end of the axon may split into several branches, which end in a pre-synaptic terminal. The electrical signals(action potential) that the neurons use to convey the information of the brain are all identical. The brain can determine which type of information is being received based on the path of the signal e Just similar to this case: I will send the some message to different medias, and the authority of each media will change the weight of what I said from the audience perspective A single neuron usually has one axon, which expands off from a part of the cell body.
