Figure 8: Rats showed different behavioral and electrophysiological responses to decreased reward value.

Figure 8:

a) The 4 × 20 task allowed for the direct comparison of a restaurant on the sub-sessions after it dispensed 3 pellets (“previous 3”; unfilled circle) and to that same restaurant when it had dispensed 3-pellets (filled circle). b) Interestingly, the rats waited as long for the previous 3-pellet restaurants as they did when the same restaurant dispensed 3-pellets on VEH (left), but not, CNO days (right). c) Though rats were willing to wait as long for previous 3-pellet restaurant, post-reward lingering revealed that 3-pellet restaurants were valued more. d) SWR rates during the Waiting epoch did not differentiate between previous 3-pellet restaurants and 3-pellet restaurants on both VEH and CNO days. e) SWR rates during the Lingering epoch were greater for the 3-pellet restaurants than the previous 3-pellet restaurants on both VEH and CNO days. VEH = blue circle, CNO = red circle.* p < 0.05; *** p < 0.001.
