Abstract: Highlights•Negative slow wave (NSW) is related to spatial working memory (SWM) load during retention•NSW in the high and low capacity groups showed divergent associations with SWM capacity and network activities•NSW was related to higher FPN activation and DMN deactivation in the high capacity group•NSW was related to greater temporal deactivation in the low capacity group•Distinct NSW-related brain networks are related to individual differences in SWM capacities
