The Brain Imaging, Behavior & Aging Lab is located in the Psychology Department of the University of Arizona and is part of the Neuroscience and Physiological Sciences Graduate Interdisciplinary programs and Evelyn F. McKnight Brain Institute.  The lab studies brain-behavior relationships in the context of aging. We use neuroimaging techniques, including structural and functional magnetic resonance imaging (MRI) and positron emission tomography (PET), in combination with measures of cognition and behavior to address research questions on cognitive aging and age-related, neurodegenerative disease.
