Experimental implementation of acquisition and extinction for the Pavlovian conditioning at different CS-US temporal relations. (a) Different cases of CS-US temporal relations. (b–g) Corresponding results of the Pavlovian conditioning experiments in different cases as indicated in the insets. The left inset is the applied training pulse pair, and the right inset shows the corresponding CS-US temporal relation. The black lines correspond to the acquisition and the red ones to the extinction. The number of training trials is 30, and the number of extinction trials is 50. The green line at 45 mV is the reference, above which the acquisition succeeds. (h) Comparison of all experimental cases in (c–g).
