Recognition memory in tree shrew (Tupaia belangeri) after repeated familiarization sessions

Abstract: Recognition memories are formed during perceptual experience and allow subsequent recognition of previously encountered objects as well as their distinction from novel objects. As a consequence, novel objects are generally explored longer than familiar objects by many species. This novelty preference has been documented in rodents using the novel object recognition (NOR) test, as well is in primates including humans using preferential looking time paradigms. Here, we examine novelty preference using the NOR ta… Show more

“…And, we thought these two indexes might be used to measure the changes of locomotor activity in tree shrews. Just like the previous study used the tracing of tree shrews’ movements to examine novelty preference for the novel object (Khani and Rainer, 2012), we also found the moving distance was significantly increased after morphine injection (Figure 6). However, this measure might not fully reflect the changes of tree shrews’ activity in the vertical direction.…”

“…We found little evidence of across-day habituation, indicating that monkeys' overall exploratory motivation for the same stimulus set remains constant over five daily sessions. This is somewhat surprising, given that across-day habituation of exploration of similar object stimuli has been demonstrated on other species including rodents (Reger et al, 2009) and tree shrews (Khani and Rainer, 2012). We suggest that exploration in the form of locomotion may be more sensitive to repetition than gaze exploration, since it involves energy expenditure and exposure to environmental risks; factors that are not associated with eye movements.…”

“…For decades, there have been many efforts to promote the tree shrew as an experimental animal and for it to replace primates in the study of fundamental biological functions and human diseases (Amako et al, 2010; Cao et al, 2003; Fang et al, 2016; Fitzpatrick, 1996; Fuchs, 2005; Khani & Rainer, 2012; Lee et al, 2016; MacEvoy et al, 2009; Nair et al, 2014; Peng et al, 1991; Pryce & Fuchs, 2017; Su et al, 1987; Veit et al, 2011, 2014; Xu et al, 2013b; Yan et al, 1996; Zhao et al, 2002; Zheng et al, 2014). Indeed, tree shrews have many characteristics that make it a good laboratory animal, such as small body size, low-cost of maintenance, short reproductive cycle and life span, and most importantly, its close relationship to primates (Fan et al, 2013; Zheng et al, 2014).…”
