TL;DR: Time-sh shifted cardiac rate timecourses were included as regressors in addition to established physiological regressors to suggest that including such time-shifted cardiac rate regressors will be beneficial for explaining physiological noise variance and will improve the statistical power in future task-based and resting-state fMRI studies.

TL;DR: In susceptibility images, the contrast of cortical layers was more consistent than in phase images and was independent of the structures' orientation relative to B0, and the mean susceptibility in these regions was significantly correlated with their estimated iron content.

TL;DR: Iron is distributed over laminae in a pattern that is suggestive of each region’s myeloarchitecture and forms the dominant source of the observed MRI contrast.

TL;DR: Results confirm the validity of using susceptibility-weighted contrast as an indicator of iron content in iron-rich brain regions and the absence of saturation effects opens the way to exploit the benefits of MRI at high field strengths for the detection of iron distributions with high sensitivity and resolution.

TL;DR: The results show that MRI resonance frequency does depend on microstructural orientation, and the spatial distribution of the resonance frequency shift suggests an origin related to anisotropic susceptibility effects rather than microscopic compartmentalization.
