Plasticity and Functional Recovery of the Brain

Cards (16)

  • What is brain plasticity?
    The brain's ability to change and adapt
  • How does functional recovery occur in the brain?
    Processes move to undamaged areas of the brain
  • What is neuronal unmasking?
    Opening dormant synapses to form new connections
  • Who conducted research on brain plasticity in taxi drivers?
    Maguire
  • What did Maguire find in his study of taxi drivers?
    Increased grey matter in the hippocampus
  • How does the duration of a taxi driver's job relate to brain structure?
    Longer job duration correlates with more grey matter
  • What are the stages of functional recovery in the brain?
    • Axonal sprouting: Growth of new nerve endings
    • Denervation supersensitivity: Compensation by undamaged axons
    • Recruitment for similar areas: Other hemisphere takes over tasks
  • What is axonal sprouting?
    Growth of new nerve endings
  • What happens during denervation supersensitivity?
    Undamaged axons compensate for damaged ones
  • What does recruitment for similar areas involve?
    Other hemisphere takes over damaged tasks
  • What are the negative effects of plasticity?
    • Prolonged drug use leads to poorer cognition
    • Amputation can cause phantom pains
  • What does prolonged drug use suggest about brain plasticity?
    It may lead to poorer cognitive function
  • What is a potential consequence of amputation related to brain plasticity?
    Phantom pains in the missing limbs
  • How does understanding functional recovery benefit medical professionals?
    It helps in offering effective treatments
  • What does cognitive reserve refer to in recovery from brain damage?
    More educated people recover better
  • What implication does cognitive reserve have on recovery from brain damage?
    Education influences the effectiveness of recovery
