Action Potential: An action potential is an electrical impulse generated by a neuron when it receives enough stimulation. It allows information to be transmitted along the neuron's axon.
Synapse: A synapse is a small gap between two neurons where communication occurs. Neurotransmitters are released from one neuron into the synapse, influencing whether or not an action potential will be generated in the next neuron.
Neural Plasticity: Neural plasticity refers to the brain's ability to change and adapt through growth and reorganization of synaptic connections. It plays an important role in learning, memory formation, and recovery after brain injury.
