    3R01NS085413-01S1
    Principal Investigator: Kevin C. Brennan, M.D.
    Institution: University of Utah
    This research project is using imaging and other tests to study migraines ? in particular how this pain disorder may be related to brain activity that re-sculpts nerve connections and circuits. The supplement will add female mice to experiments to determine the effects of sex hormones on these changes.
  • Vascular Injury and Recovery in Diabetic Ischemic Stroke
    3R01NS083559-01A1S1
    Principal Investigator: Adviye Ergul, M.D., Ph.D.
    Institution: Georgia Regents University
    This research project is studying how bleeding into the brain affects brain recovery after stroke in people with diabetes. Preliminary findings in male rats show that diabetes may worsen stroke outcomes. The supplement will conduct experiments in female rats to assess whether sex affects such outcomes.
  • The Role of MeCP2 in Rett Syndrome
    3R01NS081913-11S1
    Principal Investigator: Janine LaSalle, Ph.D.
    Institution: University of California, Davis
    Rett syndrome is a debilitating neurodevelopmental disorder caused by genetic mutation within the X-chromosome-linked gene MECP2, and it primarily affects females. This research project focuses mainly on male transgenic mice, and thus the supplement will study the characteristics and effects of this genetic mutation in female mice.
  • Novel factors for Unexplained Phenotypes of Subclinical Carotid Atherosclerosis
    3R01NS065114-04S1
    Principal Investigator: Tatjana Rundek, M.D., Ph.D.
    Institution: University of Miami
    This research project is identifying non-symptom related (subclinical) molecular markers that link atherosclerosis with stroke risk. The supplement will increase sample size by adding data from related experimental results, such that sex-specific differences in stroke risk can be accurately determined.
  • Neonatal Stroke: The Role of Microglia
    3R01NS044025-11S1
    Principal Investigator: Zinaida Vexler, Ph.D.
    Institution: University of California, San Francisco
    This research project is investigating how cells called microglia that affect immune surveillance in the brain affect the risk of stroke in newborns, which often causes substantial disability throughout life. The supplement will determine whether the sex of an infant affects his or her vulnerability to stroke and related cell and tissue injury.
