Stress and sleep disruption promote inflammation and metabolic adaptations, with important disease-modifying implications for psychiatric disorders. Using a novel chronic unpredictable sleep disruption (CUSD) paradigm, we characterised the impact of disrupted sleep and/or stress hormone exposure on locomotor behaviour and central markers of inflammation in the nucleus accumbens (NAc), a region implicated in regulation of mood, motivation and locomotor activity. Forty-eight Wistar rats (24 male; 24 female) were separated into groups exposed to combinations of CUSD/non-CUSD and corticosterone (2
