How does the action potential travel down the neuron?

To understand how neurons send electrical signals, let's start with the basics. Neurons are specialized cells that transmit information through electrical and chemical signals. The action potential is the electrical impulse that travels along the length of a neuron, carrying information from one neuron to the next. This process involves a series of complex steps, including the depolarization of the neuron's membrane, the opening of voltage-gated ion channels, and the release of neurotransmitters.

• Unintended consequences: Altering the action potential can have unintended consequences, such as disrupting normal brain function or leading to adverse reactions.
• Action potential: The depolarization triggers a rapid change in the membrane's electrical properties, generating an action potential that travels down the length of the neuron.
