PER stimulation at 11 or 30 Hz does not result in place preference or avoidance. a, b, Schematic showing the floor patterns and dimensions of the horseshoe maze (a) and the V maze (b). c, Total exploration time for the unpaired (No Stim) and paired (Stim) sides of the mazes during the postconditioning test for 11 and 30 Hz (n = 7). d, Place preference scores for the rats during preconditioning and the postconditioning test for 11 and 30 Hz. Neither frequency resulted in a place preference or a place avoidance.
