One of the basic goals of cognitive psychology is the analysis of the covert processes that
occur between stimulus and response. In the past 20–30 years, the tools available to …

Objective: To investigate the effect of vinpocetine on cerebral blood flow (CBF) in the
compromised circulation of a stroke affected hemisphere using transcranial Doppler (TCD) …

In this study, functional near-infrared spectroscopy (fNIRS) and the graph theory approach
were used to access the functional connectivity (FC) of the prefrontal cortex (PFC) in a …

Infancy is the most critical period in human brain development. Studies demonstrate that
subtle brain abnormalities during this state of life may greatly affect the developmental …

The depth at which photons penetrate into a diffusive medium before being re-emitted has
been investigated with reference to a semi-infinite homogeneous medium illuminated by a …

Near‐infrared spectroscopy (NIRS), a noninvasive optical technique, can measure changes
in hemoglobin (Hb) concentrations in brain tissue. Jöbsis first described the in vivo …

Near-infrared spectroscopy (NIRS) enables continuous non-invasive quantification of blood
and tissue oxygenation, and may be useful for quantification of cerebral blood volume (CBV) …

Functional near infrared spectro-imaging (fNIRSI) is potentially a very useful technique for
obtaining information about the underlying physiology of the blood oxygenation level …

These are exciting times for the field of optical imaging of brain function. Rapid
developments in theory and technology continue to considerably advance understanding of …

Using the modified Lambert-Beer law to analyze attenuation changes measured
noninvasively during functional activation of the brain might result in an insufficient …
