Fig. 6From: Deep brain stimulation of the nucleus basalis of Meynert modulates hippocampal–frontoparietal networks in patients with advanced Alzheimer’s diseaseCerebral glucose utilization (normalized to the whole brain) of all patients as determined by PET. a Normalized [18F] FDG uptake in different networks before and 12 months after NBM-DBS. Data are presented as the mean ± SE (n = 6), *DBS-off versus -on state, P < 0.05. b Correlation between cerebral glucose utilization in the HIPP and ADAS-Cog score, both pre-DBS and at 12 months (12 dots)Back to article page
