This work is the first to report optical intensity changes (ΔI/I≈ 0.05%) with a latency between
60 and 160ms after electrical median nerve stimulation at 5Hz detected non-invasively …

The event-related optical signal (EROS) uses near-infrared light to study changes in
neuronal optical properties in response to stimuli and endogenous events. EROS responses …

Optical imaging of intrinsic signals was performed in the barrel cortex of the rat during
whisker deflections of varying frequencies (1 to 20 Hz) and durations (0.1 to 5 s). A dose …

Near infrared spectroscopy (NIRS) can detect vascular changes in cerebral cortical tissue
elicited by functional stimulation. For some 10 years, another optical signal has been …

Fast optical signals can be used to study the time course of neuronal activity in localized
cortical areas. The first report of such signals [Gratton, G., Corballis, PM, Cho, E., Fabiani, M …

Photons are emitted during brain activity and when applied externally alter its functional
connectivity during the resting state. In the present study we applied constant or time varying …

Incorporating the wavelength dependence of the scattering effect into a simple linear
multicomponent analysis of intrinsic optical signals, we have reexamined the change in the …

Animal model studies indicate light-absorption changes of the exposed animal brain in
response to visual stimulation. Here we report observations of red-light absorbance …

Measures of parameters of the migration of near-infrared photons through the head
(attenuation, or intensity, and time-of-flight, or delay) have been proposed as a way of …

Near-infrared (NIR) spectroscopy has been used in studies of the cerebral hemodynamic
response to visual processing. In this paper, we present theoretical results from finite …
