Animals are trained to receive a painful foot shock only in a particular cage (context). When they are put in that cage 24 hours later, they will show freezing behaviour. How do hippocampal lesions affect this conditioning?

		If the hippocampus is lesioned several weeks after the conditioning, freezing in the context will be reduced.
		If the hippocampus is lesioned one day after the conditioning, freezing in the context will be reduced.
		Context fear conditioning is not affected by hippocampal lesions.
		If the hippocampus is lesioned one day after the conditioning, freezing in the context will be enhanced (increased).
