Electroencephalogram As A Diagnostic Tool In Acquired Brain Injury, Michael Zarra
Electroencephalogram As A Diagnostic Tool In Acquired Brain Injury, Michael Zarra
Senior Theses and Projects
The ability of electroencephalogram (EEG) to be used as a diagnostic device for acquired brain injuries (ABI) has been conceptualized previously. Averaged event-related potentials (ERP) derived from an EEG are suitable as markers of dysfunction however, distinctive properties in the frequency domain have not been established previously. In the present study, we examined pre- existing EEG signal data of healthy adults (HA), mild ABI (mABI), and severe ABI (sABI) human groups. Through Fourier analysis performed in MATLAB, we found that individuals in our sample population (n=80) were able to be categorized into their respective group based on common neuronal activity …

Determination Of Catecholamine Content Changes In Mouse Brain Following Chronic Ketogenic Diet, Ryan Adams
Senior Theses and Projects
This work investigated the effects of the ketogenic diet on catecholamine concentrations in the brains of mice. The ketogenic diet has been show to modulate the catecholamine concentrations in the cerebrospinal fluid of children as well as altering hippocampal norepinephrine levels in mice. Tissue homogenates of the motor cortex, somatosensory cortex, nucleus accumbens, anterior caudate, posterior caudate and midbrain regions were analyzed using high pressure liquid chromatography to quantitate norepinephrine, dopamine, 3, 4-dihydroxyphenylacetic acid (DOPAC), 5-hydroxyindoleacetic acid (5HIAA), homovanillic acid (HVA) and serotonin (5-HT). No significant differences in catecholamine concentration levels were detected in the tissue homogenates. Analysis of metabolite …
