MAOA KO mice do not display alterations in sensory function. (a, b) MAOA KO mice exhibit comparable latencies to reach a cliff and locate buried food in the visual cliff and buried food tests, respectively. (c, d) In the novel object interaction and recognition task, MAOA KO mice (■) show comparable exploratory activity and percent novelty exploration indices compared to WT mice (□) in the absence of light, indicating intact microvibrissae function. All values are represented as means ± S.E.M. %NEI, Percent novelty exploration index.
