The CNS Lab is affiliated with the Clinical Psychology and Behavior and Brain Science programs in the Department of Psychology and the multidisciplinary Neuroscience Program at the University of Georgia. The CNS lab integrates multimodal neuroimaging and neuropsychological assessments with other clinical research methodology to examine brain-behavior relationships as they pertain to neuropsychiatric disorders. The CNS Lab specializes in experimental design, and data acquisition, analyses, and interpretation for clinical studies that employ functional magnetic resonance imaging (fMRI), perfusion MRI (arterial spin labeling techniques), and structural morphometry (e.g., volumetrics, cortical thickness, lesion quantification). The CNS Lab is responsible for data analyses and consultation for several local and multi-site clinical research studies. Current projects vary from methodological development to empirically driven clinical research (e.g., aging, cardiovascular disease, addiction, obesity, chronic stress).
