Popis: The systemic administration of low reserpine (RES) doses (0.1–1.0 mg/kg) has been proposed as a valuable rat model for the study of non-motor symptoms of Parkinson’s disease (PD). Here, we investigated the temporal-dependent effects of RES (1 mg/kg, s.c.) on short-term memory and locomotion, as well as, the levels of dopamine, serotonin and its metabolites in the striatum, hippocampus and prefrontal cortex at 3, 24 or 72 h after RES administration. RES administrations resulted in social and object recognition memory impairment and increased dopamine turnover in the striatum, without changes in the rat spontaneous locomotor activity, 3 h after RES administration. Altogether, these results provide new insights for the use of RES administration as an experimental design for the study of PD non-motor symptoms in rats.
