Fig. 4From: Characterization of an eutherian gene cluster generated after transposon domestication identifies Bex3 as relevant for advanced neurological functionsBex3 mutant mice display an array of behavioral and cognitive alterations. Adult control and Bex3 mutant mice were subjected to a comprehensive battery of behavioral tests. a Locomotor activity (number of broken beams) and total repetitive behaviors (number of grooming and rearing) were evaluated in a 5-min open field test. b Social behavior was assayed in the three-chambered test. Sniffing times are showed in social familiar and social stranger phases. c Social organized behaviors were tested by the nesting building assay. d Sensory motor integration was determined by prepulse inhibition of acoustic reflex. e The Y-maze test was performed to evaluate repetitive conducts, attention, and/or working memory. As alternance, the % of triplets was determined. f Novel object recognition memory was evaluated 24 h after a training session. A positive discrimination index in this memory test indicates novel object preference exploration. g The passive avoidance test was used to evaluate emotional cognition. Entry latencies to the dark compartment in training and memory testing sessions are shown. Results are presented as mean ± SEM (N = 6 mice per experimental group); *p < 0.05, **p < 0.01, ***p < 0.005, ****p < 0.001, one-way ANOVABack to article page
