For formalin-injected rats, (A) a correlation is seen between licking behavior and activity in the brain region associated with that behavior (jaw and upper lip) suggesting that the behavior is reflective of the brain activity. (B) No correlation is seen with hindlimb behavior and the primary somatosensory (S1) hindlimb cluster activity suggesting behavior is not a sole explanation for increased brain activity.
