Impacts of NMN supplementation on neurobehavioral alterations in mice following subacute and sub-chronic PM exposure. Legends Neurobehavioral assessments were conducted following subacute and sub-chronic PM exposure using the tests of open field and the Morris maze. Various indices, including (A) escape latency, (B) platform area crossings, (C) time in target quadrant, (D) time in central squares, (E) route in the central squares, and (F) overall distance, were examined and analyzed. The results were presented as mean ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001
