task 6

Question 1

ACC lesions affect decision making about whether it is worth making an effortful action given the value of the expected outcome.

Answer 1

 ACC encodes value of outcomes

 Works with ventral Striatum to mediate cost benefit decisions and persistence in accomplishing a goal

Question 2

sag

Answer 2

The SFG is involved in task switching when changes have to be made to the way how that responses are selected (encodes response selection rules). Lesions to the SFG impair the switching between response sets ( necessary for task switching if it involves a response change)
SFG in task control: involves anticipatory preparation and selection of a task set

Question 3

conclusion Rushworth

Answer 3

• ACC:
  o Detects when actions have led to errors
  o Cost-benefit calculations of actions
  o Associate actions with reinforcement consequences (positive and negative)
• SFG:
  o Monitor response conflict before error commission
  o Rostral SFG: Select action sets
  o Most important when action sets are initiated or changed, both for task-switching paradigms (stimulus-response selection rules) and sequencing paradigms (response-response selection rules)
