Temporal relationship of conditioned stimulus (CS; trace b), unconditioned stimulus (US; trace c), and analysis periods during the unilateral classical eyeblink conditioning (EBCC) in guinea pigs. In a CS-US paired trial, we analyzed the parameters of conditioned response (CR; 200-ms period before the US onset) and unconditioned response (UR; 200-ms period after the US onset). These responses were based on the average amplitude of baseline activity (350-ms period before the CS onset). An example of a typical CR and UR from a guinea pig is shown (trace a).
