neuropsych

• What is the focus of the video on neuropsychology?

  Introduction to neuropsychology
• How do cognitive psychologists contribute to understanding the brain?

  They create theories on information processing
• What do cognitive neuroscientists combine in their research?

  Brain structure and information processing
• What is an important aspect of cognitive neuroscience research?

  Identifying the location of brain functions
• What historical method was used to study brain function?

  Investigating abnormal brains
• What can be inferred from brain damage and functional differences?

  The damaged part is responsible for that function
• Who is Phineas Gage?

  A man with a metal bar through his frontal lobe
• What change occurred in Phineas Gage after his accident?

  He developed an aggressive personality
• What part of Clive Wearing's brain was damaged?

  His hippocampus
• What was Clive Wearing unable to do due to his brain damage?

  Make new long-term memories
• What area of the brain is associated with Broca's area?

  The temporal lobe
• What limitation exists when studying abnormal brains?

  Sample size is often only one person
• What is the focus of modern neuropsychological research?

  How a healthy brain functions
• What does CT stand for in CT scans?

  Computed tomography
• What do CT scanners use to produce images?

  A series of x-rays
• What is a major advantage of CT scans?

  They are cheaper to perform
• What is a serious drawback of CT scans?

  They pose a radiation risk
• What does PET stand for?

  Positron emission tomography
• How do PET scanners detect brain activity?

  By detecting gamma rays from a tracer
• What is a key advantage of PET scanners?

  They show brain activity
• What is a limitation of PET scans?

  They involve radioactive tracers
• What does fMRI stand for?

  Functional magnetic resonance imaging
• How does an fMRI scanner measure brain activity?

  By measuring oxygenated blood flow
• What is a major advantage of fMRI scans?

  They do not use radiation
• What is a drawback of fMRI scans?

  Images are slightly delayed
• What did Tulving's study using a PET scanner investigate?

  The connection between memory types and brain structure
• How many participants were involved in Tulving's study?

  Six participants
• What did Tulving find regarding episodic and semantic memories?

  They use separate brain regions
• What is a limitation of Tulving's study regarding sample size?

  Only six participants were included
• What is neurological damage?

  Destruction of brain neurons
• What can cause neurological damage?

  Strokes and physical damage
• What happens if the motor cortex is damaged?

  Paralysis of the controlled body part
• What does contralateral mean in relation to brain damage?

  Opposite side paralysis occurs
• Which area of the brain controls decision-making?

  The frontal lobe
• What does the limbic system regulate?

  Emotional responses
• What are the scanning techniques used in neuropsychology?

  • CT (Computed Tomography)
  • PET (Positron Emission Tomography)
  • fMRI (Functional Magnetic Resonance Imaging)
• What are the advantages and disadvantages of CT, PET, and fMRI scans?

  CT:

  • Advantage: Cheaper, high detail
  • Disadvantage: Radiation risk, no activity shown

  
  

  PET:

  • Advantage: Shows brain activity
  • Disadvantage: Radioactive tracers, limited scans

  
  

  fMRI:

  • Advantage: No radiation, shows activity
  • Disadvantage: Delayed images, poor temporal resolution
• What are the implications of neurological damage on behavior and motor abilities?

  • Damage to motor cortex causes paralysis
  • Frontal lobe affects decision-making
  • Limbic system influences emotional responses
• What are the key findings from Tulving's study on memory?

  • Semantic and episodic memories are separate
  • Different brain regions are activated for each
  • Small sample size limits generalizability
