Complexity analysis of heartbeat-related signals in Brain MRI time series as a potential biomarker for ageing and cognitive performance

Abstract: There are multiple magnet resonance imaging (MRI) based approaches to studying the ageing brain. Getting older affects both the structure of the brain and our cognitive capabilities but there is still no solid evidence on how ageing influences the mechanisms underlying the MRI signal. Here, we apply a recently developed long-range zero-quantum coherence (ZQC) weighted MRI sequence that was found to be sensitive to wakefulness. We found that the complexity of the signal time curve is also affected by age. While… Show more
