Temporal stability of the hemodynamic response function across the majority of human cerebral cortex
Sign Up to like & getrecommendations! Published in 2022 at "Human Brain Mapping"
DOI: 10.1002/hbm.26047
Abstract: The hemodynamic response function (HRF) measured with functional magnetic resonance imaging is generated by vascular and metabolic responses evoked by brief (70%, with lesser reliability observed in some areas of prefrontal cortex). HRFs were measured… 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.
