Experimental Design
Between 15:00h and 18:00h animals from the experimental groups received a single pCPA (Sigma Aldrich, 2015) i.p. injection (dose 300 mg/kg), solved in sterile saline. After pCPA administration residents were housed individually in their homecages until RVI test day, which was performed six days later. Then animals were euthanised and OB were obtained for neurochemical and genetic analysis.
