I often wonder if some of the results showing rats navigating a maze for a primary reward could be the results of prior rats leaving a trail of a specific scent. I am assuming that a rat rewarded at one arm of a maze would leave a scent associated with a reward and this becomes a discriminative stimulus for the others.-
