Figure 3From: Hippocampal CA1/subiculum-prefrontal cortical pathways induce plastic changes of nociceptive responses in cingulate and prelimbic areasField potentials evoked by CA1/subiculum stimulation. A: A field potential recorded in the PFC was composed of a positive wave with a 6 ms peak latency and a negative wave with a 16 ms peak latency. HFS delivered to CA1/SB increased the amplitude of the positive waves. B: Potentiation of field potentials started within 10 min after HFS and returned to the control value in approximately 90 min.Back to article page
