Background and objective Blood oxygenation level-dependent (BOLD) functional MRI (fMRI) has been extensively used as a marker of brain dysfunction and subsequent recovery following stroke. However, growing evidence suggests that straightforward interpretation of BOLD fMRI changes with aging and disease is challenging. In this study, we investigated the effect of calibrating task fMRI data by applying a hemodynamic calibration method using the resting-state fluctuation amplitude (RSFA). Task… 

Separating vascular and neuronal effects of age on fMRI BOLD signals

Emerging evidence that vascular mechanisms in the brain do not simply control blood flow to support the metabolic needs of neurons, but form complex neurovascular interactions that influence neuronal function in health and disease is highlighted.

Multimodal fusion analysis of functional, cerebrovascular and structural neuroimaging in healthy aging subjects

It is proposed that integrating multiple neuroimaging modalities allows to better characterize brain pattern variability and to differentiate brain changes in healthy ageing.

A multimodal approach to investigate brain reorganization after spinal cord injury using functional magnetic resonance imaging and functional near-infrared spectroscopy

This dissertation is one of the first studies to comprehensively examine both the structural and functional alterations of the brain in humans with complete SCI and opens promising avenues for SCI research using fNIRS modality.

A Review on Treatment-Related Brain Changes in Aphasia

It is observed that language recovery is not only associated with changes in traditional language-related structures in the left hemisphere and homolog regions in the right hemisphere, but also with more medial and subcortical changes (e.g., precuneus and basal ganglia).

Hospitalisation for COVID-19 predicts long lasting cerebrovascular impairment: A prospective observational cohort study

The results indicate chronic cerebrovascular impairment following severe acute COVID-19, with the potential for long-term consequences on cognitive function and mental wellbeing.

Reducing vascular variability of fMRI data across aging populations using a breathholding task

These findings may lead to a method to identify vascular reactivity‐induced differences in the BOLD response across populations and the development of methods to account for the influence of these vasculature differences in a simple, noninvasive manner.

Effects of aging on cerebral blood flow, oxygen metabolism, and blood oxygenation level dependent responses to visual stimulation

It is concluded that when comparing two populations, the BOLD response can provide misleading reflections of underlying physiological changes and a calibrated approach provides a more quantitative reflection of underlying metabolic changes than the Bold response alone.

Results suggest increased activation in acute stroke in right hemisphere language regions; healthy controls conversely show less activation in these regions; Additionally, activity in brain areas significantly correlated with behavior.

The effect of ageing on fMRI: Correction for the confounding effects of vascular reactivity evaluated by joint fMRI and MEG in 335 adults

The scaling analysis revealed that much of the effects of age on task‐based activation studies with fMRI do not survive correction for changes in vascular reactivity, and are likely to have been overestimated in previous fMRI studies of ageing.

The Effect of Normal Aging on the Coupling of Neural Activity to the Bold Hemodynamic Response

The overall finding that some aspects of the hemodynamic coupling between neural activity and BOLD fMRI signal change with age cautions against simple interpretations of the results of imaging studies that compare young and elderly subjects.

Functional magnetic resonance imaging (fMRI) has rapidly emerged as a powerful tool for studying brain function, despite the fact that it measures neuronal activity indirectly, through the
