recommendations! Published in 2025 at "Brain Topography"

DOI: 10.1007/s10548-025-01107-0

Abstract: Functional magnetic resonance imaging (fMRI) is a widely used tool to investigate the functional brain responses in living humans. Valid comparisons of fMRI results depend on consistency of the blood-oxygen-level-dependent (BOLD) hemodynamic response function (HRF).… read more here.

DOI: 10.1016/j.euroneuro.2017.12.086

Abstract: Introduction There is need to validate the fMRI analysis methods using large-scale datasets [1]. It is known that the hemodynamic response function (HRF) varies across brain regions and subjects [2]. Different HRF models are currently… read more here.

DOI: 10.1117/1.nph.9.3.032205

Abstract: Abstract. Significance: Although emerging evidence suggests that the hemodynamic response function (HRF) can vary by brain region and species, a single, canonical, human-based HRF is widely used in animal studies. Therefore, the development of flexible,… read more here.

recommendations! Published in 2023 at "Stroke"

DOI: 10.1161/strokeaha.122.041880

Abstract: Background: Functional magnetic resonance imaging (fMRI) is ubiquitously used to study poststroke recovery. However, the fMRI–derived hemodynamic responses are vulnerable to vascular insult which can result in reduced magnitude and temporal delays (lag) in the… read more here.

DOI: 10.3389/fneur.2022.1038700

Abstract: Transcranial electrical stimulation (tES) can modulate the neurovascular unit, including the perivascular space morphology, but the mechanisms are unclear. In this perspective article, we used an open-source “rsHRF toolbox” and an open-source functional magnetic resonance… read more here.
