“…The methods include activity chamber (Pierce & Kalivas, 2007;Thomas, Marcaletti, & Feige, 2011), open field (Seibenhener & Wooten, 2015), treadmill (Leblond, L'Esperance, Orsal, & Rossignol, 2003), and running wheel (Thomas et al, 2011). The duration of recordings of animal activity ranged from five minutes to several hours (Pierce & Kalivas, 2007;Thomas et al, 2011). This variety of experimental conditions led to inconsistent conclusions (Douglas & Isaacson, 1964;McNaughton et al, 1983;Swerdlow et al, 2001;Degoulet et al, 2008;Kropff, Carmichael, Moser, & Moser, 2015).…”
