Strengths and Weaknesses

• What are the two main weaknesses of ERPs?

  Low spatial resolution and background noise
• What is the temporal resolution of ERPs?

  High temporal resolution
• What does high temporal resolution in ERPs allow researchers to do?

  Pinpoint when the brain processes information
• What do ERPs reflect?

  Brain's reaction to a specific stimulus
• What are the temporal and spatial resolutions of different brain imaging techniques?

  • ERPs: High temporal, Low spatial
  • fMRI: Low temporal, High spatial
  • PET: Low temporal, Medium spatial
  • MEG: High temporal, Medium spatial
• What is the trade-off between temporal and spatial resolution in brain imaging techniques?

  Higher temporal resolution often means lower spatial resolution
• How does fMRI differ from ERPs in terms of spatial resolution?

  fMRI shows where brain activity occurs with high resolution
• How are ERPs recorded?

  Using electrodes placed on the scalp
• What is the effect of background noise on ERPs?

  It can mask brain activity and interfere with results
• What are the key strengths of ERPs compared to other brain imaging techniques?

  • High temporal resolution
  • Non-invasive nature
  • More precise timing than fMRI
  • Less costly and simpler to use
• How does the temporal resolution of MEG compare to that of ERPs?

  Both MEG and ERPs have high temporal resolution
• How do ERPs compare to fMRI in terms of spatial resolution?

  ERPs have low spatial resolution compared to fMRI
• How is recording ERPs similar to using a stethoscope?

  Both are simple, safe, and effective methods
• What is the relationship between spatial resolution and degree of immobility shown in the image?

  • As spatial resolution increases, the degree of immobility also increases
  • Techniques with higher spatial resolution (e.g. fMRI/DTI) require the subject to remain more still compared to techniques with lower spatial resolution (e.g. EEG/ERP)
• What does ERP stand for in brain imaging techniques?

  Event-Related Potentials
• How do the neuroimaging techniques shown in the image differ in terms of their degree of immobility required?

  • Techniques with higher spatial resolution (e.g. fMRI/DTI) require the subject to remain more still
  • Techniques with lower spatial resolution (e.g. EEG/ERP) allow for more subject movement
• What is the temporal resolution of PET scans?

  Low temporal resolution
• What are the two major strengths of ERPs?

  High temporal resolution and non-invasive
• What does the abbreviation "fNIRS/TCDS" stand for in the image?

  Functional Near-Infrared Spectroscopy/Transcranial Direct Current Stimulation
• What are the neuroimaging techniques shown in the image?

  • MEG
  • EEG/ERP
  • fNIRS/TCDS
  • PET
  • fMRI/DTI
• What is the spatial resolution of fMRI?

  High spatial resolution
• How do ERPs compare to fMRI in terms of timing precision?

  ERPs provide more precise timing of brain activity
• What do small changes in electrical activity in ERPs indicate?

  Brain's reaction to the stimulus
• How does the spatial resolution of fMRI/DTI compare to the other neuroimaging techniques shown in the image?

  fMRI/DTI has the highest spatial resolution among the techniques shown
• What are the advantages of ERPs over fMRI in terms of cost and complexity?

  ERPs are less costly and simpler to use
• What does the abbreviation "EEG/ERP" stand for in the image?

  Electroencephalography/Event-Related Potentials
• How can low spatial resolution in ERPs be compared to observing city lights?

  It shows active areas but not specific buildings
• What is the spatial resolution of MEG?

  Medium spatial resolution
• What is the trade-off between ERPs and fMRI regarding brain activity information?

  ERPs provide precise timing but less location detail
• What is the spatial resolution of PET scans?

  Medium spatial resolution
• What does the abbreviation "MEG" stand for in the image?

  Magnetoencephalography
• What does low spatial resolution in ERPs imply?

  ERPs indicate when brain activity occurs, not where
• What is the primary purpose of Event-Related Potentials (ERPs)?

  • Measure brain activity
  • Assess responses to specific stimuli
  • Analyze cognitive processes
• What does low spatial resolution in ERPs imply?

  It provides less detail about brain location
• What are Event-Related Potentials (ERPs)?

  Measures of brain activity in response to stimuli
• How can high temporal resolution in ERPs be compared to watching a movie?

  It allows seeing every detail like slow motion
• How is background noise in ERPs similar to listening to music?

  It makes it harder to concentrate on the melody
• What is the temporal resolution of fMRI?

  Low temporal resolution
• Why are ERPs considered non-invasive?

  They don't harm the brain during recording
