Neuron firing, also known as an action potential or nerve impulse, is the process of a neuron sending an electrical signal down its axon to another cell. It occurs when the cell's electrical charge changes and reaches -55 mV, triggering an "all or nothing" response. Here's a simplified overview of the process: Dendrites: Receive information from other neurons and pass it to the soma. Soma: Processes the information and decides if it's important enough to pass on. Action potential: When the cell's charge reaches -55 mV, an action potential fires. Axon: The action potential travels down the axon, insulated by myelin, to the next cell. Refractory period: After firing, the neuron has a brief period where it can't fire again.
