    Brain's ability to reorganize and modify
  • How does neuroplasticity relate to learning?
    It enables new skills through neural connections

    Process of neuron communication via neurotransmitters
  • What triggers an action potential in a neuron?
    Combined signals exceeding a threshold
  • What happens at the axon terminals during neurotransmission?
    Neurotransmitters are released into the synapse
