Action Potential: An electrical signal generated by a neuron when it receives sufficient stimulation, resulting in the transmission of information down its axon.
Neurotransmitters: Chemical messengers released by neurons into synapses that bind to receptors on receiving neurons, allowing for communication between them.
Reuptake: The process in which neurotransmitters are reabsorbed by the sending neuron after they have transmitted their signal, helping regulate neural communication.
