Using a bilateral common carotid artery stenosis model in mice, we showed that electroacupuncture (EA) significantly improved cerebral blood flow (CBF) and working memory in VCI mice, which may be associated with an increase in norepinephrine concentration in the PFC and heightened neuronal activity in both the PFC and the LC. Additionally, activation of the LC-PFC circuit via chemogenetic manipulation mimicked the effects of EA on improving CBF in VCI mice. Conversely, inhibiting the LC-PFC circuit blocked the therapeutic effects of EA.
