CNRM hosts a monthly seminar series that features presentations from experts in the traumatic brain injury (TBI) research community. These seminars are critical because they give current and future experts within the TBI community an opportunity to gather together and exchange ideas. By working together, we can all make a difference in TBI research. See below for more information about previous and upcoming CNRM seminars. 

September 2019 

Date: 09/10/19
Arthur J. and Marcella McCaffray Professor in Alzheimer’s Disease
Professor of Psychiatry and Behavioral Science
University of Washington School of Medicine
Title: "Glymphatic Pathway Dysfunction in Neurodegenerative Disease: Translational and Clinical Studies"
Presentation Summary: The glymphatic system contributes to the clearance of proteins, including tau, alpha synuclein, and amyloid beta, from the brain interstitium during sleep. Dr. Iliff's group has reported that glymphatic function is slowed in the aging and post-traumatic brain, and he will present new findings suggesting that impairment of glymphatic function promotes the formation of aggregates and aggregate propagation in mouse models of neurodegeneration. Lastly, Dr. Iliff will present on findings from studies in human subjects suggesting that impairment of glymphatic function may contribute to the development of neurodegenerative conditions, including Alzheimer’s disease.

Georgia State University, Georgia Institute of Technology, Emory University
Title"Functional Connectivity: Current and Future Directions" 
Presentation Summary: Since the discovery of the blood-oxygen-level-dependent (BOLD) contrast there has been a considerable amount of work focusing on correlations of BOLD signals from two brain regions. The magnitude of the correlation indicates the level of functionally connectivity between the regions. Functional connectivity studies have shown that a single BOLD correlation assessment cannot accurately describe the brain because of its temporal dynamic characteristic. Capturing the time variations occurring in the brain is better assessed by a dynamic functional connectivity (dFC) approach. In this framework, dFC is represented by a sequence of correlations varying as time progresses. The dFC signal has revealed a new level of functional effects linked to known diseases. For instance, traumatic brain injury produces abnormal temporal variations of dFC which recover with time until the dFC temporal patterns become similar to healthy individuals. The dFC framework has also allowed the use of time-dependent techniques for the analysis of the brain. Dr. Vergara will present a summary of the neuroscience application of these newer methods that includes information theory, random matrices, and sequences of dFC mind states.

July 2019 

Date: 07/25/19
Title: "Advances in the CHIMERA Animal Model of Traumatic Brain Injury" 
Presentation Summary: Dr. Wellington's presentation will describe new studies using the Closed Head Impact Model of Engineered Rotational Acceleration (CHIMERA), an animal model of TBI that places equal emphasis on the biomechanical and neurological relevance to human TBI. She will also describe new design features for the CHIMERA platform and give an overview of her TBI translational activities spanning CHIMERA and human neurotrauma.  

June 2019 

Date: 06/19/19
Associate Professor; James and Gaye Pigott Endowed Chair of the Department of Neurological Surgery
Research Director, The Sports Institute 
University of Washington, School of Medicine 
Title: "Combat-related Concussion: Understanding Trajectories of Long-term Clinical and Imaging Outcomes"
Presentation Summary: This presentation will feature findings from a prospective, observational, and longitudinal research study that followed Service Members from the point of injury in combat out to 1-year, 5-year, and, now, 10-year outcomes. Known as the EVOLVE study (EValuation Of mild TBI Long-term outcome in Active-Duty US Military and VEterans) the effort focused on elucidating the effects of mild brain injury sustained in combat to outcomes and connecting the dots through repeated evaluations over the first decade post-injury. Results from both the advanced neuroimaging and extensive battery of neurological, neuropsychological, and psychiatric outcomes collected in these patients will be presented.
Peter Basser, Ph.D. 
Title"Mean Apparent Propagator (MAP) MRI: Potential Applications to Imaging TBI?" 
Presentation Summary: Dr. Basser and Dr. Butman will review their recent work, performed within CNRM, in developing and implementing a novel diffusion MRI pipeline to try to detect TBI in a clinical setting. 

 May 2019 

Date: 05/01/19
Co-Founder & Chief Science Officer
Title: "Cerebrovascular Assessments after Traumatic Brain Injury"
Presentation Summary: Dr. Hamilton’s presentation discussed the various capabilities of Neural Analytics’ Transcranial Doppler Ultrasound System. This portable system noninvasively assesses post-concussive cerebrovascular reactivity by measuring blood flow changes in the brain.
Date: 05/21/19
Brian Cox, Ph.D.
Professor of Pharmacology & Neuroscience, Uniformed Services University
Chair, CNRM’s Biospecimen Repository Steering Committee
Raha Dastgheyb, Ph.D.
Research Associate, Department of Neurology
Johns Hopkins University School of Medicine
Title: "Mass-Spectrometric Analysis of Lipids in Brain & Blood after TBI: Lipids as Potential Biomarkers for TBI"
Presentation Summary: This presentation will discuss findings from Dr. Cox's recently completed CNRM funded project, “Plasma Lipid Biomarkers for Traumatic Brain Injury.” This project compared blood lipid profiles among various subject groups:
  • Subjects with mild TBI and “injury positive” magnetic resonance imaging (MRI) scans
  • Subjects with mild TBI and “injury negative” MRI scans
  • Age/gender-matched controls with no history of TBI
  • Impact-related TBI within civilian subjects
  • Blast-related TBI within military subjects
This project’s objective was to determine if changes in specific lipids or lipid profiles correlated with injury type (e.g., cause), severity, location, and clinical outcomes.
