REM sleep EEG slowing signals basal forebrain integrity in older adults with subjective and mild cognitive impairment
Introduction The basal forebrain is an early site of pathology in Alzheimer's disease (AD). Within this region, the nucleus basalis of Meynert (NbM) provides the primary cholinergic input to the neocortex and supports cortical activation during rapid eye movement (REM) sleep. REM electroencephalography (EEG) slowing is...
