Abstract Background Coenzyme Q10 (CoQ10) is a key mitochondrial electron carrier and a widely used dietary supplement with potential neurological benefits. However, the mechanisms underlying its effect in ameliorating memory deficits caused by cerebellar injury are not fully understood.

Methods Network pharmacology analysis was used to identify genetic targets of CoQ10 i
