ways of studying the brain

    Cards (28)

    • What does fMRI stand for?
      Functional magnetic resonance imaging
    • What is the primary use of fMRI?
      To measure brain activity during tasks
    • How does fMRI detect brain activity?
      By detecting radio waves from magnetic fields
    • What does an EEG record?
      Tiny electrical impulses from brain activity
    • How can EEG help diagnose brain conditions?
      By measuring characteristic wave patterns
    • What are event-related potentials (ERPs)?
      Electrophysiological responses to specific events
    • How are ERPs isolated from EEG data?
      Through statistical analysis of EEG data
    • What is the purpose of post-mortem examinations?
      To analyze the brain after death
    • Why are post-mortem examinations conducted in psychological research?
      To link behaviors to brain abnormalities
    • What is the main purpose of brain scanning techniques?
      To investigate localization of brain functions
    • How does fMRI work in terms of blood flow?
      It detects changes in blood oxygenation and flow
    • What does fMRI produce to show brain activity?
      Three-dimensional images of brain activity
    • What is a key strength of fMRI?
      It does not use radiation
    • What is a limitation of fMRI?
      It has poor temporal resolution
    • What is a key strength of EEG?
      It has extremely high temporal resolution
    • What is a limitation of EEG?
      It cannot pinpoint exact neural activity sources
    • How do ERPs improve upon EEG?
      They provide more specificity in measurements
    • What is a limitation of ERP methodology?
      Lack of standardization between studies
    • What is a strength of post-mortem examinations?
      They provide foundational understanding of brain processes
    • What is a limitation of post-mortem examinations?
      Causation issues may arise from observed damage
    • Why is consent an issue in post-mortem studies?
      Participants may not provide informed consent
    • How do fMRI and EEG differ in terms of temporal resolution?
      fMRI has poor temporal resolution, EEG has high
    • How do ERPs and EEG relate to each other?
      ERPs are derived from EEG measurements
    • What is the relationship between post-mortem examinations and brain disorders?
      They help link disorders to brain damage
    • How did early researchers like Broca and Wernicke use post-mortem studies?
      To establish links between brain and behavior
    • What ethical issues arise from post-mortem examinations?
      Consent from individuals before death is needed
    • What is the significance of studying HM's brain post-mortem?
      To identify areas linked to memory deficits
    • How does the specificity of ERPs benefit cognitive neuroscience?
      It allows measurement of cognitive functions accurately
