Welcome to the Minority Health and Health Disparities International Research Training (MHIRT) Program at CBU.

Brazil - Locations: Belem, Curitiba, Emas/Pantanal, Florianopolis, and Sao Paulo.

Belem: One laboratory, 2 student positions available

Project description: Basic research on visual psychophysics.  The research will involve visual testing of people.  The tests will consist of contrast sensitivity and visual evoked potentials.

2009 Project Title: Amplitude of P100 Visual Evoked Cortical Potential (VECP) as Function of Achromatic Contrast Stimulus in Glaucomatous Patients.

2008 Project Title: Influence of Luminance Contrast in the Amplitude of Multifocal Visual Evoked Potentials
