Background: Spatially resolved spectroscopy is a recently developed technique for
noninvasive monitoring of cerebral tissue oxygenation using the photon diffusion theory …

Near infrared spectroscopy (NIRS) is used to measure global changes in cerebral
haemodynamics. We have adapted the technique to measure regional changes in response …

Methods for measuring cerebral blood volume (CBV) have traditionally used radioisotopes.
More recently, near-infrared spectroscopy (NIRS) has been used to measure CBV by using …

Functional cranial near-infrared spectroscopy (NIRS) has been widely used to investigate
the haemodynamic changes which occur in response to functional activation. The technique …

Brain activity is associated with changes in optical properties of brain tissue. Optical
measurements during brain activation can assess haemoglobin oxygenation, cytochrome-c …

The aim of this study was to find out whether a correlation exists between changes in brain
tissue oxygen pressure (ti-p 02) and hemoglobin oxygenation (Hb02) measured by near …

Near-infrared 700-950 absorbance of some chromophores has been measured in different
biological tissues, in particular rat and rabbit brain, to assess value of this noninvasive …

The potential of near infrared spectroscopy (NIRS) to detect vascular changes in cerebral
cortical tissue elicited by functional stimulation has been established (1). The vascular …

The letter-fluency task-induced response over the prefrontal cortex is investigated bilaterally
on eight subjects using a recently developed compact, eight-channel, time-resolved, near-IR …

We compared pharmacologically-perturbed hemodynamic parameters (cerebral blood
volume; CBV, and flow; CBF) by acetazolamide administration in six healthy human subjects …
