Auditory pavlovian threat conditioning. Top panel: an auditory conditioned stimulus (CS) is paired with a foot shock unconditioned stimulus (US). Middle panel: when the CS is presented in a novel context, it elicits a conditioned reaction, freezing. Bottom panel: if the CS is not paired with the US it does not elicit freezing during the test.
