Neurotransmitters: Neurotransmitters are chemical messengers that transmit signals between neurons. They play a crucial role in regulating mood, behavior, cognition, and other brain functions. Examples of neurotransmitters include dopamine, serotonin, and acetylcholine.
Plasticity: Neuroplasticity refers to the brain's ability to reorganize and adapt throughout life in response to experiences, learning, and environmental changes. This phenomenon allows the brain to recover from injuries, form new neural connections, and learn new skills.
