October 4, 2024: Ellyn A. Riley, Ph.D., CCC-SLP

Pre-Frontal tDCS to Improve Language and Attention in Aphasia - video coming soon!

Dr. Ellyn Riley studies acquired speech and language disorders, improving treatment outcomes for persons with aphasia, the role of fatigue in stroke recovery, and neuromodulation as a tool to enhance speech and language therapy.

In the lab, we use behavioral and physiological measures, applied linguistic theory, and neuromodulation techniques to study language and cognitive factors, changes in neurophysiology, and communicative barriers that can influence recovery for persons with aphasia. Our goal is to improve recovery outcomes and quality of life for persons with aphasia and their families.

September 4, 2024: Inge Leunissen, Ph.D.

Modulating Inhibitory Control Non-Invasively with Transcranial Alternating Current Stimulation - video coming soon!

Dr Leunissen is an Assistant Professor of Cognition and Cognitive Neuroscience and Faculty of Psychology and Neuroscience at Maastricht University. Inhibitory control over unwanted thoughts, emotions, and movements is essential for effective interaction with our environment. This becomes particularly evident when there is too little inhibition, as in obsessive-compulsive disorder or Tourette’s syndrome, or too much, as in Parkinson’s disease. Recent evidence links successful inhibition to the power of neural oscillations in the beta band (15-30Hz) in a circuit involving the frontal cortex and the subthalamic nucleus. Here, Dr. Leunissen will present data from a series of electrical stimulation experiments, in both healthy volunteers and in Parkinson’s patients undergoing surgery for deep brain stimulation, demonstrating that both the power and phase of these beta oscillations causally relate to successful inhibition. Finally, Dr. Leunissen will illustrate the clinical relevance of these findings and how her team has used them to develop a novel closed-loop tACS treatment approach for inhibitory control disorders.

February 2, 2022: Simon Davis, Ph.D.

Modulating Memory Network Dynamics in Healthy & Pathological Aging

Our understanding of the cortical mechanisms that contribute to healthy cognition as we age is an exciting and nascent domain of knowledge. Such an understanding of such patterns in healthy aging is a precondition to the effective treatment of age-related disorders like Alzheimer's disease. For example, the notion that older adults rely on a more bilateral system of brain regions (relative to younger adults) to maintain cognitive function has become generally well accepted. Nonetheless, the compensatory role of bilateral activation remains controversial because most of the data supporting this idea is correlational, and fails to actively engage these bilateral networks. Understanding the importance and malleability of such cross-hemispheric communication in cognition will likely provide a clear path for developing novel therapies to ameliorate age-related cognitive decline. In this talk I will present neuroimaging, neurophysiology, behavioral and TMS data that highlights this and other age-related mechanisms by which older adults may continue to perform tasks successfully, and how these mechanisms may be encouraged by noninvasive neuromodulation.

Dr. Simon Davis is an Assistant Professor in the Department of Neurology at Duke University, as well as the co-Director of Duke Brain Stimulation Research Center and the Director of the Neuroimaging Core: Bryan Alzheimer’s Disease Research Center. His research includes age-related reorganization during episodic memory, executive functions, and semantic processes, cross-hemispheric communication during episodic and semantic memory in younger and older adults, myelination in the aging brain, and its role in cognitive decline and connectivity during episodic memory processes using neuromodulation.
