Studies using other rodent attentional tasks have reported beneficial attentional effects of comparable doses of AMPH or MPH (Berridge et al. 2006, 2012; Tomlinson et al. 2014; Turner and Burne 2016; Navarra et al. 2017; MacQueen et al. 2018; Caballero-Puntiverio et al. 2019; Young et al. 2020) as well as in a genetic ADHD-like mouse model (Nilsson et al. 2018) and prefrontal cortex lesioned animals (Chudasama et al. 2005), although not in all studies (Ding et al. 2018; Caballero-Puntiverio et al. 2020). This evidence concerns the gene AMPH and attention deficit-hyperactivity disorder.
