Normal locomotor, anxiety and weight changes during learning session. (A) Decreased distance traveled across trials shows that both groups successfully acclimated and were familiar with the environment. (B) Time spent in the center zone during the behavior was not altered by treatment, showing that viral protein R (Vpr) did not affect anxiety. (C) Normal rat weight (grams) gain shows no difference throughout the experiment or by treatment. Acc, acclimation; NL, novel location; NO, novel object.
