Association of plasma amyloid-β oligomerization with theta/beta ratio in older adults

BackgroundOligomeric Aβ (OAβ) is a promising candidate marker for Alzheimer’s disease (AD) diagnosis. Electroencephalography (EEG) is a potential tool for early detection of AD. Still, whether EEG power ratios, particularly the theta/alpha ratio (TAR) and theta/beta ratio (TBR), reflect Aβ burden—a primary mechanism underlying cognitive impairment and AD. This study investigated the association of TAR […]

Interpreting Rhythm as Parsing: Syntactic‐Processing Operations Predict the Migration of Visual Flashes as Perceived During Listening to Musical Rhythms

Abstract Music can be interpreted by attributing syntactic relationships to sequential musical events, and, computationally, such musical interpretation represents an analogous combinatorial task to syntactic processing in language. While this perspective has been primarily addressed in the domain of harmony, we focus here on rhythm in the Western tonal idiom, and we propose for the […]

Machine learning classifiers and associations of cognitive performance with hippocampal subfields in amnestic mild cognitive impairment

BackgroundNeuroimaging studies have demonstrated alterations in hippocampal volume and hippocampal subfields among individuals with amnestic mild cognitive impairment (aMCI). However, research on using hippocampal subfield volume modeling to differentiate aMCI from normal controls (NCs) is limited, and the relationship between hippocampal volume and overall cognitive scores remains unclear.MethodsWe enrolled 50 subjects with aMCI and 44 […]
