Deep brain stimulation (DBS) of the nucleus basalis of Meynert (NBM) has been shown to exert promising therapeutical effects in a pilot study with patients suffering from Alzheimer's disease (AD). We aimed at comparing the cognitive effects of intermittent and continuous NBM stimulation paradigms in an animal model for AD. In this exploratory study, aged Tgf344-AD rats were behaviorally tested pre-, and post implantation, while being stimulated with unilateral- or bilateral-intermittent and bilateral-continuous patterns. Bilateral-intermittent NBM DBS lead to supernormal performance in a spatial memory task. These findings suggest that NBM DBS could be further refined, thereby improving patient care.
