GHRL and Anxiety: In the FOOD ACCESS paradigm we did not detect any change in anxiety-like behavior between ghrelin-treated (1 μg) and saline-treated groups, as there was no significant difference in the time spent in the open arms (Fig. 6B) or the number of entries into the open arm (saline: 4.8±1.2 vs. ghrelin: 5.7±1.4).
