George (Ron) Mangun, Ph.D.

Dr. Mangun is Professor of Psychology and Neurology and was the founding Director of the Center for Mind and Brain and former Dean of Social Sciences. His research focuses on several key mechanisms involved in attention and awareness. This work takes a cognitive neuroscience approach to investigating how we perceive, attend, ignore and become aware of our environment. For example, recordings of event-related brain potentials (ERPs) from healthy persons and special patient groups are obtained while they perform various perceptual and attentional tasks. The ERPs provide high temporal resolution indices of specific stages of human information processing, and thus can be used to investigate the underlying mechanisms of mental function. To identify the brain systems and circuits involved in various attentional processes, tools such as functional magnetic resonance imaging (fMRI) are used in conjunction with the ERPs.

​​John Olichney, M.D.

Dr. Olichney is Professor of Neurology. He directs the Cognitive Electrophysiology and Neuroimaging (CEAN) laboratory of in the Center for Mind and Brain. He develops electrophysiological and neuroimaging techniques sensitive to the memory and language impairments characteristic of neurodegenerative disorders such as Alzheimer’s disease (AD). The techniques his laboratory uses to study the physiology of memory processes include Cognitive Event-Related Potentials (ERPs) and functional Magnetic Resonance Imaging (fMRI). Cognitive ERPs, comprised of summated synaptic electrical potentials, are a powerful tool for investigating the timing of cognitive processes. Functional MRI demonstrates the precise anatomical substrates of cognition, by mapping the regional changes in brain oxygenation. Dr. Olichney has been applying these techniques to further our understanding of the memory decline seen with aging, neurodegenerative disease (e.g., Alzheimer’s disease) and other neurological disorders (e.g., alcoholic Korsakoff’s syndrome). The physiological markers of memory and language dysfunction that he employs have been shown to help predict which patients with Mild Cognitive Impairment will progress to develop clinical Alzheimer’s disease or dementia.


​​Charan Ranganath, Ph.D.

Dr. Ranganath is Professor of Psychology. His research concerns the neurocognitive structure of human memory and executive control. One set of studies currently underway concerns the relationship between short-term, or working memory, and long-term memory. Results from event- related fMRI studies conducted by Dr. Ranganath suggest that overlapping regions of the prefrontal cortex and medial temporal lobes are active during both working memory and long-term memory tasks. This research suggests that a common neural system supports both of these types of memory. Currently, Dr. Ranganath is investigating how different regions within the prefrontal cortex and medial temporal lobes contribute to working and long-term memory through additional fMRI studies of healthy young adults and behavioral testing of patients with focal brain damage. A second, related area of interest is the role of prefrontal cortex in the control and evaluation of information in memory. Finally, in collaboration with Dr. Andy Yonelinas, Dr. Ranganath is investigating the roles of different medial temporal lobe regions in recognition memory processes. To address this issue, he is conducting parallel studies using event-related fMRI and event-related brain potentials in healthy young and older adults and amnesic patients with medial temporal lobe damage. In collaboration with another research group, Dr. Ranganath is also conducting studies to examine field potentials recorded directly from the human hippocampal formation in patients performing recognition memory tasks.

Julie Sutcliffe, Ph.D.

Dr. Sutcliffe’s is Professor of Biomedical Engineering and Internal Medicine. Her research complements Dr. Cherry’s work through the design, synthesis and in vivo evaluation of targeted molecular imaging agents with a focus on PET. Her group has developed rapid radiolabeling technologies using both solid-phase and solution-phase chemistries to incorporate the short half-life PET radionuclide 18F into peptides. Peptide-based radiopharmaceuticals are gaining extensive attention as targeted molecular imaging agents. It is therefore important that technologies are developed that allow these agents to be synthesized rapidly and screened both in vitro and in vivo to assess their efficacy. Dr. Sutcliffe’s group uses two approaches to develop targeted molecular imaging agents to image cell surface receptors A “rational approach” based on known binding structures and a “random approach” using the one-bead-one-compound molecular library methodology. Peptides are synthesized using standard Fmoc chemistries, screened in vitro for affinity and selectivity and subsequently radiolabeled and screened in vivo using small animal imaging. Dr. Sutcliffe has recently developed a new “first in human” PET facility to directly translate novel ligand development into clinical research and is currently working with Dr. DeCarli on the clinical application of AV-45 (amyloid beta) and AV-1451(tau) ligands for the study of cognitive aging.

​​​Andy Yonelinas, Ph.D.

Dr. Yonelinas is Professor of Psychology. His research examines the processes underlying human memory. In order to characterize the functional nature of different memory processes he is currently using implicit and explicit tests as well as several 'second generation' procedures such as the process dissociation procedure, the independence remember/know procedure, and ROC modeling procedure.
