To fill this gap in knowledge, longitudinal testing using Novel Object Recognition (NOR), Novel Object Location (NOL), and Object in Place (OiP) paradigms was used to determine whether and when Pink1–/– rats express deficits similar to the impairments in visual recognition memory and//or visuospatial information processing that commonly occur in PD patients (Owen et al., 1993; Higginson et al., 2005; Possin et al., 2008; Fang et al., 2020; Fernandez-Baizan et al., 2020). This evidence concerns the gene PINK1 and Parkinson disease.
