6.5.3 Evaluation of Plasticity and Recovery

    Cards (33)

    • What is neural plasticity?
      Brain's ability to change
    • Functional recovery is the process by which the brain compensates for damaged areas.
    • After a stroke, the brain may rewire itself to compensate for damaged areas.
    • Functional recovery is the brain's ability to compensate for damaged areas by remapping functions to undamaged regions.
    • Order the reasons why evaluating plasticity and recovery is crucial:
      1️⃣ Assessing the extent of recovery
      2️⃣ Identifying factors that influence recovery
      3️⃣ Developing interventions to enhance recovery
      4️⃣ Measuring the impact of treatments
      5️⃣ Improving patient outcomes
    • Match the researcher with their study and key finding:
      Merzenich et al. (1984) ↔️ Brain maps can reorganize after sensory input changes
      Kolb (1999) ↔️ Smaller lesions have better recovery outcomes
      Gauthier et al. (2000) ↔️ Expertise leads to enhanced brain activity
    • What does neural plasticity involve at the synaptic level?
      Strengthening or weakening connections
    • Learning a new language is an example of neural plasticity.
    • Evaluating plasticity and recovery is unnecessary for improving patient outcomes.
      False
    • What is neural plasticity?
      Brain's ability to adapt
    • Functional recovery refers to the brain's ability to compensate for damaged areas
    • Evaluating plasticity is crucial for assessing recovery after brain injury.
    • Match the researcher with their key finding:
      Merzenich et al. (1984) ↔️ Brain maps can reorganize after sensory input changes
      Kolb (1999) ↔️ Smaller lesions lead to better recovery outcomes
      Gauthier et al. (2000) ↔️ Expertise enhances brain activity in specific areas
    • Which researcher demonstrated that sensory input changes can reshape brain maps?
      Merzenich
    • Research on plasticity often uses real-life scenarios to increase ecological validity.
    • Brain imaging techniques like fMRI provide evidence of brain activity and plasticity
    • What is one potential bias in plasticity research that affects generalizability?
      Experimenter bias
    • Functional recovery involves the brain compensating for damage by reassigning tasks to unaffected regions.
    • What is an example of neural plasticity in real life?
      Learning a new language
    • Relearning speech after a stroke is an example of functional recovery
    • Order the key reasons for evaluating plasticity and recovery:
      1️⃣ Assessing recovery extent
      2️⃣ Identifying influential factors
      3️⃣ Developing interventions
      4️⃣ Measuring treatment impact
      5️⃣ Improving patient outcomes
    • Evaluating plasticity is essential for understanding how much brain function has been restored after an injury.
    • What did Merzenich et al.'s (1984) study on monkey finger mapping demonstrate about the brain?
      Brain maps can reorganize
    • Kolb's (1999) research showed that smaller lesions result in better recovery
    • What did Gauthier et al.'s (2000) study on face recognition experts find?
      Expertise enhances brain activity
    • Merzenich's research highlights the brain's adaptability to sensory input changes.
    • Research on plasticity and recovery often uses real-life scenarios to achieve high ecological validity
    • What do longitudinal studies in plasticity research track over time?
      Changes in brain activity
    • Brain imaging techniques like fMRI provide direct evidence of brain activity during learning.
    • Match the weakness of research with its explanation:
      Potential Biases ↔️ Selection or experimenter bias affects results
      Small Sample Sizes ↔️ Limits statistical power and reliability
      Generalization Limitations ↔️ Results may not apply broadly
    • What is informed consent in plasticity research?
      Understanding study purpose and risks
    • Special care must be taken to protect vulnerable populations, such as cognitively impaired individuals
    • Participants in plasticity research have the right to withdraw from the study at any time.
