Age-Related Low Frequency Amplitude Differences in Resting-State Blood Oxygenation Level-Dependent Signal in the Cerebellum

Author(s): Korte JA; Steele CJ; Joiner WM; Fan AP;

There is a growing interest to study cerebellar contributions to aging outside of traditional sensory processing and motor tasks. While cerebellar aging analyses typically utilize functional connectivity (FC) to study functional differences with age, this study aimed to identify a marker of healthy aging based on resting state blood oxygenation level depe ...

Modeling venous bias in resting state functional MRI metrics

Author(s): Huck J; Jäger AT; Schneider U; Grahl S; Fan AP; Tardif C; Villringer A; Bazin PL; Steele CJ; Gauthier CJ;

Resting-state (rs) functional magnetic resonance imaging (fMRI) is used to detect low-frequency fluctuations in the blood oxygen-level dependent (BOLD) signal across brain regions. Correlations between temporal BOLD signal fluctuations are commonly used to infer functional connectivity. However, ...
