Amedi and coworkers used fMRI to investigate the differences between brain activation for perception and imagery. Their findings showed that when participants were , some areas associated with non-visual sensation (such as hearing and touch) were .
 
  a. using visual images; activated
  b. using visual images; deactivated
  c. perceiving stimuli; activated
  d. perceiving stimuli; deactivated

Question 2

Ganis and coworkers used fMRI to measure brain activation for perception and imagery of objects. Their results showed that
 
  a. there is no difference between the activation caused by perception and by imagery.
  b. perception and imagery activate the same areas near the back of the brain, but imagery activates more of the frontal lobe than does perception.
  c. perception and imagery activate the same areas of the frontal lobe, but imagery activates more of the back of the brain than perception does.
  d. perception and imagery activate the same areas of the frontal lobe, but perception activates more of the back of the brain than imagery does.
