Figure 7: Rats showed behavioral and electrophysiological differences to changes in reward value.

Figure 7:

a) In addition to measuring when a restaurant increased from 1 to 3 pellets, we also measured different variables after the restaurant dispensed 3 pellets (“previous 3”) (i.e. currently dispensing 1 pellet (filled circle), but dispensed 3 pellets on a previous sub-session of that day (unfilled circle)). b) The rats waited for 1-pellet restaurants similarly as long as previous 3-pellet restaurants on both VEH (left) and CNO days (right). c) Interestingly, post-reward lingering revealed that previous 3-pellet restaurants were valued more than 1-pellet restaurants, as the rats lingered longer at these restaurants post reward consumption. d) SWR rates during the Waiting epoch were greater for previous 3-pellet restaurants on both VEH (left) and CNO (right) days. e) SWR rates during the Lingering epoch did not differentiate between previous 3-pellet restaurants and 1-pellet restaurants on VEH days (left), though it did on CNO days (right). VEH = blue circle, CNO = red circle. * p < 0.05; ** p < 0.01; *** p < 0.001.
