Fear conditioning is one of the most common methods to measure memory in rodents. It exploits the Pavlovian association between an unpleasant unconditioned stimulus (shock) to a conditioned neutral stimulus (sound cue). The reaction of rodents, as predated animals, is to freeze (stay immobile) when exposed to fearful situations, such as a shock.
Once the association has happened and the animal has memorized it, freezing will happen also when the sound is presented without shock. This is the principle of Fear Conditioning, which is also coupled to the change of the visual/tactile context (appearance) to ensure that the animal is reacting to the association to the sound and not to the environment (cued and contextual fear conditioning)
