  • All animals had been subjected to 24-h MD at PND3 or control treatment. Half of the animals were treated with MIF through oral gavage twice daily on PND26–PND28; the other half received VEH. Data represent mean ± SEM; all groups n = 11-12 animals. Visits to the arm are expressed as a fraction of the total number of trials.
