Valentine Leslie Marcar

Ph.D, Neuropsychology

I am a researcher specializing in visual information processing and imaging brain activity using evoked potentials (EEG) and blood oxygenation level dependent (BOLD) signal changes (fMRI & fNIRS). My current focus is to understand the relationship between stimulus property, neural response and the evoked potential or BOLD signal. I am presently investigating the relationship between the visual evoked potential and retinal damage due to arterial hypertension and diabetes. My aim is to diagnose retinal damage before clinical symptoms arise and so preserve the highest possible level of vision in these patients.
