BDNF in the hippocampus. BDNF was measured in the hippocampus of animals given one of the five treatments (SAL, MA, FS, ISO, or WEIGH). No differences in BDNF were observed among treatments on P11 regardless of treatment or time point assessed (top). On P15, BDNF was increased in MA-administered animals, regardless of time assessed (bottom). *** = P < 0.001 compared with all other treatments.
