Fig. 4From: Subclinical epileptiform discharges in Alzheimer’s disease are associated with increased hippocampal blood flowAssociation between normalized rCBF in hippocampus and spike frequency as measured with ear-EEG. Simple linear regression was applied to test if spike frequency was associated with the normalized mean rCBF in the hippocampus in patients with AD (p < 0.001)Back to article page
