How do memory systems cope with situations where a large amount of information has to be remembered? One solution is to separate the information into chunks to facilitate learning. We propose that in the hippocampus, sensory cues can parse spatial representations coded by hippocampal units thereby facilitating spatial learning.To test this hypothesis, mice were trained on a difficult spatial task in a large environment: they had to learn the positions of water rewards on a double cheeseboard maze, with two sets of rewards on two separate platforms. These rewards contained either no odour (NO-O
