Fig. 2From: Altered social behavior and ultrasonic communication in the dystrophin-deficient mdx mouse model of Duchenne muscular dystrophySocial behavior in the three-chambered test. Top panels show the experimental setup during (a) exploration of the apparatus that only contained empty confining tubes (habituation; trial 1), (b) choice between a stranger mouse and an object (sociability; trial 2), and (c) choice between a familiar and a novel mouse (preference for social novelty; trial 3). Histograms represent exploratory behavior during the three trials, expressed as percent time spent in central and side (left, right) chambers during habituation; (a) percent time spent sniffing the tubes containing the mouse (black bars) and the object (white bars) during the sociability test and (b) percent time spent sniffing the familiar (black bars) and novel mice (white bars) during the social novelty test; (c) *p < 0.05Back to article page
