<p>Low-dose/low-stress exposure does not alter body weight, anxiety-like behavior, or cognition in rats.</p>

No significant differences were observed between groups. <b>(B, C) Open-field test</b>: time spent in the center (B) and total distance traveled (C). <b>(D) Elevated plus maze</b>: percentage of time spent in the open arms. <b>(E, F) Light–dark transition test</b>: latency to enter the dark compartment (E) and percentage of time spent in the light compartment (F) (n = 11–12/group). <b>(G, H) Novelty-suppressed feeding test</b>: food consumption (G) and latency to feed (H) (n = 10–12/group). <b>(I, J) Recognition memory tests</b>: discrimination index for novel object location (I) and novel object recognition (J). <b>(K, L) Barnes maze training</b>: latency to find the escape hole (K) and time spent in the target quadrant (L). <b>(M, N) Barnes maze re-training</b>: latency to locate the new escape hole (M) and time spent in the new target quadrant (N) one week later. <b>(O) Barnes maze memory recall</b>: time spent in the original target quadrant during the re-training probe.

No significant differences were observed between groups in any behavioral measure.</p>
