Current Research: Our mission is to improve the lives of our patients who suffer from Chronic Fatigue Syndrome, Gulf War Illness, and other idiopathic conditions. We aim to understand the underlying mechanisms that lead to the chronic nature of pain and fatigue through: Non-invasive functional magnetic resonance imaging (fMRI) brain scans, Serial changes in bodily fluids following a physiological stressor, Alterations in autonomic control.

Current Research: Learning in context. I study the transfer of learning as a function of environmental conditions. I have a line of research examining learning from television, books and touchscreens during infancy and early childhood. I also study how bilingual exposure influences transfer of learning.
Associate Professor, Center for Neuroscience Research
Joshua Corbin Laboratory
Education: B.A. Rutgers University; Ph.D. University of North Carolina-Chapel Hill
Current Research: The Corbin lab studies the genetic and cellular basis of the normal and abnormal development of the mammalian amygdala. Despite an extensive understanding of amygdala function and anatomy, currently little is known regarding the development of this complex structure, and how altered development of the amygdala contributes to the phenotypes observed in developmental disorders such as Autism Spectrum Disorders and Fragile X Syndrome. To address these questions, we use the mouse as an experimental model, employing both standard and cutting edge embryological, transgenic, electrophysiological, and optogenetic approaches. The ultimate goal of the studies in our lab is to understand the link between developmental events and the assembly of the mature amygdala at a genetic, cellular, structural, and functional level.

Education: M.D. University of Maryland, 1986
Current Research: My research focuses on human subjects research in people with stroke and arm amputation. I use clinical populations to ask questions about the nature of motor recovery or acquisition of prosthesis skill, changes in brain physiology, and alterations in health-related behaviors. Techniques used include clinical trials, neuroimaging, upper extremity biomechanics, transcranial magnetic stimulation, and measurement methodology. I collaborate with colleagues at National Rehabilitation Hospital, Georgetown University, Catholic University, and nationally.

Current Research: Dr. Greenwald’s research employs behavioral and magnetic resonance imaging (MRI) methods to investigate specific cognitive functions (e.g., visuo-spatial cognition, language, attention) and their functional neuroanatomy. She works with patients who have acquired brain injury at different points in life (e.g., stroke during the perinatal period, during childhood, or in adulthood) as well as neurologically healthy controls. Her long-term goal is to improve assessment tools and rehabilitation options for patients with cognitive impairments.

Current Research: Organization of cortical processing of auditory stimuli, studied with fMRI and single-unit recordings in non-human primates. Processing stimulus identity and meaning in auditory ventral stream. Auditory-motor integration in the dorsal stream. Gating and control of auditory input.

Current Research: Much of his research and publications have addressed the role of sleep disturbance in the pathogenesis and treatment of PTSD. His current RO-1 research studies patients who are being treated for traumatic injuries and includes early sleep recordings and longitudinal assessment of PTSD. This work has led to several recent publications of sleep-related and other predictors of the early development of PTSD.

Current Research: In drug-resistant (refractory) epilepsy the alternative option is limited to surgery however, this is not always a viable option. We explore the potential therapeutic effects of novel modalities in particular hypothermia and cortical stimulation for these patients. We study the effects of hypothermia (cooling) in slice models of epilepsy in Dr. Stefano Vicini’s laboratory. We have shown that cooling can terminate epileptiform discharges in these models with no discernible tissue damage. We have explored the cellular mechanisms of action of hypothermia in particular a possible differential effect on interneurons vs. pyramidal cells. We are also studying the role of high frequency oscillations (HFOs) in epilepsy and cognitive processing. We plan to investigate the potential disease modifying (antiepileptogenic) effects of hypothermia with the goal of establishing a Georgetown Center for Advanced Epilepsy Research in collaboration with Drs. in Drs. Jian Yong Wu, Andrei Medvedev, Patrick Forcelli, and outside investigators. We are also exploring the characteristics of seizure onset focus and epileptogenesis as well as the possibility of using cortical stimulation for treatment of insomnia.

Current Research: I currently have two lines of research. My primary research interest involves investigating frontal lobe abnormalities in children with temporal lobe epilepsy. Specifically using neuropsychological testing to characterize these abnormalities as well as fMRI to understand the functional network abnormalities that underlie this frontal lobe dysfunction. My secondary research interest involves examining the effect of sleep on concussion and associated cognitive dysfunction.
Associate Professor, Pharmacology
Education: B.S. Xavier, 1993; Ph.D. Vanderbilt, 2000
Current Research: My varied research interests include determining the mechanisms governing synaptic transmission in the dorsal striatum using electrophysiological, genetic and biochemical methods. The striatum is a crucially important brain region involved in the smooth execution of motor control and other various functions. Disruptions in striatal physiology result in debilitating motor problems exemplified by Parkinson’s disease and Huntington’s disease. My research goals are to more fully understand the complex interactions of small molecule neurotransmitters in the striatum. These include investigating the relationships and crosstalk among glutamate, dopamine, acetylcholine and endocannabinoids governing normal and pathological states which dictate striatal output.

Current Research: The emphasis of research in my laboratory is on understanding the brain neurocircuits that regulate the function of the upper gastrointestinal tract such as those that control gastric tone and motility. To this end, we employ varied approaches that include microinjection of chemical substances in the brain, recordings of end organ function, patch-clamp electrophysiology in brain slices and neuroanatomical tract tracing.

Robert P. Yasuda
Assistant Professor, Pharmacology & Physiology
Education: Ph.D. University of Colorado, 1986
Current Research: My laboratory is involved in the study of the structure and function of neuronal nicotinic receptors in the brain that are composed of five protein subunits that act as ligand-gated ion channels. These receptors are thought to be involved in the ncotine addition seen in smokers. We utilize molecular biological, biochemical and electrophysiological methods to study these receptors. Specifically, we are interested in understanding the nature of the nicotine binding site and how the order of these nicotinic receptor subunits affects function. One approach we are currently using is the creation of concatamers of the nicotinic receptor subunits that allow us to make receptors composed of subunits of known order and composition.

Current Research: Our lab exploits the unique investigative opportunities provided by intracranial recordings during neurosurgical procedures. Using electrodes captured from epilepsy patients implanted with subdural and depth electrodes, we investigate the activation of cortical networks during memory encoding and recall. And using recordings captured during the implantation of deep brain stimulators, we investigate the role of the basal ganglia in learning and decision-making.
