ease remember to answer this question based on our class lectures. in a fear conditioning experiment, you have trained rats that the sound of a tone leads to mild foot shock, so that the rats will exhibit a conditioned fear response (freezing) when they hear the tone. in the next phase of the experiment, you now teach the rats that that the tone no longer results in foot shock. if you block neural activity in the during this phase of the experiment, the rats will not be able to learn that the tone is now safe, and will continue to exhibit freezing.
