Non-invasive optical imaging of stroke.

The acute onset of a neurological deficit is the key clinical feature of stroke. In most cases, however, pathophysiological changes in the cerebral vasculature precede the event, often by many years. Persisting neurological deficits may also require long-term rehabilitation. Hence, stroke may be considered a chronic disease, and diagnostic and therapeutic efforts must include identification of ...

Non-Invasive Determination of Blood Glucose Levels by Optical Waveguide

Objective: Today, there are various non-invasive techniques available for the determination of blood glucose levels. In this study, the level of blood glucose was determined by developing a new device using near-infrared (NIR) wavelength, glass optical waveguide, and the phenomenon of evanescent waves. Materials and Methods: The body's interstitial fluid has made possible the development of ne...

Non-invasive optical spectroscopy and imaging of human brain function.

Brain activity is associated with changes in optical properties of brain tissue. Optical measurements during brain activation can assess haemoglobin oxygenation, cytochrome-c-oxidase redox state, and two types of changes in light scattering reflecting either membrane potential (fast signal) or cell swelling (slow signal), respectively. In previous studies of exposed brain tissue, optical imagin...

Non-invasive imaging of non-linear interactions

Interactions between neuronal assemblies form a basis for the mechanism of functional integration that underlies most of our actions. Studying these interactions is important for understanding the principles of brain operation. However, such neuronal communications are hallmark of a living brain and therefore it is of paramount importance to develop tools for imaging of these interactions on th...
