2. What is the method for fMRI studies about fear?

  • It is measured how blood flow changes with expression intensity but blood flow is not compared for fear and neutral expressions
  • Participants are asked about the expression and the activated brain areas are recorded alongside their response
  • With facial expressions, blood flow is either compared for fear and neutral expressions, or measured how blood flow changes with expression intensity
  • With facial expressions, blood flow is either compared for fear and neutral expressions but it is not measured how blood flow changes with expression intensity

3. Which is the largest part of the amygdala in humans?

  • Neither, they are approximately the same size
  • Basolateral cortex of the amygdala > Central nucleus of the amygdala
  • Basolateral cortex of the amygdala < Central nucleus of the amygdala

4. How are fMRI studies into the insula and disgust carried out?

  • A facial expression is presented to the participant and the blood flow between disgust and neutral expressions is compared
  • Participants are asked about the expression and the activated brain areas are recorded alongside their response
  • Participants are asked to imitate the facial expression inside the scanner and the activated brain areas are recorded
  • A facial expression is presented to the participant and the blood flow of disgust and neutral expressions is recorded

5. What does the Limbic theory (1937) propose?

  • The insula and amygdala have a neural circuit which mediates emotion
  • It is a neual circuit of the cingulate cortex, hippocampus, anterior thalamus and hypothalamus that control our emotion
  • The orbitofrontal cortex and amygdala have a neural circuit which mediates emotion
  • It is a neual circuit of the prefrontal cortex, hippocampus, superior thalamus and hypothalamus that control our emotion
