The effect of unilateral AP5 infusions into the PRH and mPFC on object-in-place performance. a, AP5 infusion into the PRH has no effect on object processing after a short retention delay; thus, the disruption only occurs unilaterally within the neural network, and behavioral performance remains intact. b, AP5 infusion into the PRH disrupts object processing after a long delay. As the network is disrupted bilaterally, performance in the object-in-place task is impaired.
