Homebase behavior of zebrafish in novelty-based paradigms

Assessing Social Engagement in Heterogeneous Groups of Zebrafish: A New Paradigm for Autism-Like Behavioral Responses

“…A promising approach is to analyze the spatial and kinematic patterns in more detail. For instance, as one of the reviewers suggested, it might be interesting to look at homebase formation [49], [50]. In this study, we did not systematically investigate this aspect of the MK-801 zebrafish, since homebase behavior is not easy to assess in shoals of fish and because it is not directly related to the new paradigm presented here, which focuses on social cohesion.…”

“…S1 and S2). It should be pointed out that spatial allocation is not identical with homebase behavior, since the latter also takes into account traveled distance in and number of visits to the spatial zones (or cells) under consideration [49], [50]. The examples (Fig.…”

Zebrafish (Danio rerio) behaviour is largely unaffected by elevated pCO2

“…In order to quantify thigmotaxis (‘wall-hugging’), the arena was divided into a wall zone (defined as the outermost 4 cm of the arena) and an inner zone (the rest, or centre of the arena; Gerlai et al ., 2000; Maximino et al ., 2010). To quantify the number of home bases, the function ‘Heatmap Visualization’ inside Ethovision XT10 was applied to each individual trial, and the number of home bases were counted as the number of red and/or dark red areas in the arena, which are indicative of a long presence of the subject's centre point in that area (Stewart et al ., 2010). …”

“…The open field test used in this study is a widely used test to investigate exploratory behaviour and anxiety as well as activity level (Blaser and Gerlai, 2006; Grossman et al ., 2010; Maximino et al ., 2010; Stewart et al ., 2010), behaviours which have been reported to be affected in the presence of elevated CO 2 levels (Munday et al ., 2010, 2013; Cripps et al ., 2011). The detour test was chosen because it provides a test of brain function for different decision-making tasks (Vallortigara and Rogers, 2005).…”

Animal Personality Relates to Thermal Preference in Wild-Type Zebrafish,Danio rerio

“…6,27,30,31 Learning and memory, aggression, anxiety and stress, shoaling behavior, and social reaction are fields in which the use of zebrafish has exponentially increased. [32][33][34][35][36][37] The aim of the present study was to compare the final thermal preferendum of proactive and reactive adult wildtype (WT) zebrafish (D. rerio). In addition, we recorded the levels of differential distribution along the gradient from temperature choice (T Ch ) versus temperature restricted (T R ) conditions.…”
