“…For example, magnetoencephalography (MEG) distinguishes Alzheimer's disease pathology from frontotemporal lobar degeneration by their spectral signatures, while retaining functional anatomical concordance with the clinical syndromes ( Sami et al., 2018 ). The brain's evoked and induced responses as measured by MEG and electroencephalography (EEG) distinguish Alzheimer's disease from controls, in advanced disease ( Sitnikova et al., 2018 ), mild cognitive impairment stage ( Dauwels et al., 2010 , Hughes et al., 2019 ), and even presymptomatically in carriers of autosomal dominant mutations ( Ochoa et al., 2017 , Suarez-Revelo et al., 2016 ). The spectral features of noninvasive clinical studies recapitulate invasive and ex vivo recordings of transgenic model systems ( Koss et al., 2016 , Kurudenkandy et al., 2014 , Sami et al., 2018 ).…”
