1. Blood Volume and Oxygenation Changes in the Forearm Muscles of Stroke Patients Measured Using Non- Invasive Surface Near-Infrared Spectroscopy PI: Mahsa Ranji Presenter: Jeffrey Sugar

2. Principles of The Method Wavelength (nm) Ε (molar extinction Coefficient) Beer-Lambert Law: I(t,λ) I0(λ)I0(λ) LiLi Using Several Wavelengths of light we can model the unknown concentrations as a Linear Regression Model  Optical path length is related to the source- detector distance:

3. Instrumentation Hemi paretic Stroke Survivors Have There Blood Oxygenation Levels analyzed as they perform a light digital workout The Results Have shown that The oxygenation levels are significantly affected on the paretic side of the patient. This effect is not observed in Control subjects

4. Cytochrome C Oxidase Cytochrome C Oxidase Is an Important Enzyme in the Metabolic Cycle. Analyzing this chemical will allow for analysis of metabolic activity during neurological disturbances. Ex-vivo studies have been performed to extract the ratio of reduced vs oxidized cytochrome c oxidase while in the presence of Blood
