Suppose that the necessary and sufficient constraints are respected and that a stimulus predicting reward (CS+) is followed by a reward (US+) 20 consecutive times (from t1 to t20) at t20 if we present a CS+ and then withhold the US+, what will the DA activation pattern look like?at t20 if we present a CS+ and then withhold the US+, what will the DA activation pattern look like?

a) firing for CS+ and no firing for US+

             b) firing for CS+ and firing for US+

             c) depression for CS+ and firing for US+

             d) firing for CS+ and depression for US+

Please explain

Solution

Solution: firing for CS+ and no firing for US+
Explanation: After CS-US conditioning, the CS produces the rise in rewards thus there wille be firing for CS+ and no firing for US+
