Effects of Carotid Artery Compression Test on Regional Cerebral Blood Volume, Hemoglobin Oxygen Saturation and Cytochrome-C-Oxidase Redox Level in Cerebrovascular Patients

The roles of changes in deoxyhemoglobin concentration and regional cerebral blood volume in the fMRI BOLD signal

“…To (Ferrari et al, 1986(Ferrari et al, , 1987(Ferrari et al, , 1992. This agrees with the known fact that under normal conditions in healthy subjects the ratio of the [tHb] to rCBV (the hematocrit) does not change significantly during short periods of time such as the duration of typical functional activation experiments.…”

Cerebral haemoglobin oxygenation during sustained visual stimulation – a near–infrared spectroscopy study

“…We used a NIRO-500 system (Hamamatsu Photonics KK, Japan) to continuously measure changes in [oxy-Hb] and [deoxy-Hb] through the intact skull in reflection mode (Ferrari et al 1986 ;Elwell et al 1992). Light emitted from four laser diodes (wavelengths of 775, 825, 850, and 904 nm) was carried to the subject's head via an optical fibre (optode).…”

Computer simulation of time-resolved optical imaging of objects hidden in turbid media

“…the so-called therapeutic window: Near-infrared light is not as strongly absorbed by human tissue than visible light [4,42] and so will have higher transmission and less likelihood of causing burns. Near-infrared transillumination can be used to look at the structure and function of biological systems [43,44] and is now used for various applications including the monitoring of blood oxygenation in tissue [45], muscle oxygenation [46,47] and physiology [48], brain oxygenation in new-born infants [2,[49][50][51][52] and adults [53,54], and the flow of blood and specific chemicals, such as oxyhaemoglobin or glucose, in arteries close to the surface of the skin. The latter provides a noninvasive way for diabetics to monitor their blood glucose levels [2,[55][56][57].…”
