Figure 5.

Effect of odor-shock conditioning on fine-grain temporal pattern of freezing and respiration during odor presentation in infant pups. The temporal pattern is represented with a 1-s bin precision, from the odor onset (green vertical line on each graph) to shock arrival (red and blue vertical line on each graph) for the paired groups. Point B on the x-axis represents the averaged baseline. Paired 20 s group: red (n = 10), Paired 30 s group: blue (n = 10) and Odor group: green (n = 10). Filled circles on each curve indicate the points that are significantly different from the baseline (p < 0.05).
