Behavior graph of FraidyRat in a session with 4 conditioning and 30 extinction trials. The top panel reflects freezing as a function of time (freezing—stillness—is up). Bottom panel shows the CSs (thin green line) and USs (thin red line) as they were delivered in time. The bottom-most line reflects the context in which FraidyRat was placed. In this example, he was conditioned in context A (blue line) and extinguished in B (red line).
