The Role of Systemic Physiology in Individual Hemodynamic Responses Measured on the Head Due to Long-Term Stimulation Involving Colored Light Exposure and a Cognitive Task: An SPA-fNIRS Study [PDF]
Brain Sciences, 2022 In our previous investigations using systemic physiology augmented functional near-infrared spectroscopy (SPA-fNIRS) neuroimaging, we found larger variability between subjects in changes of cerebral hemodynamics and oxygenation induced by an intricate ...

Individual Differences in Hemodynamic Responses Measured on the Head Due to a Long-Term Stimulation Involving Colored Light Exposure and a Cognitive Task: A SPA-fNIRS Study [PDF]
Brain Sciences, 2021 When brain activity is measured by neuroimaging, the canonical hemodynamic response (increase in oxygenated hemoglobin ([O2Hb]) and decrease in deoxygenated hemoglobin ([HHb]) is not always seen in every subject.

Hemodynamics and vascular oxygenation measured at the forehead during changes in respiration: A SPA-fNIRS study [PDF]
Respiratory Physiology and NeurobiologySignificance: Cerebral blood flow is influenced by respiration, primarily through changes in the CO₂ concentration of arterial blood. Aim: The objective of this study was to investigate the effect of changes in arterial CO₂ concentration induced by respiratory changes on oxygenation and hemodynamics in the cerebral and extracerebral tissue layers of ...
