The Cognitive Neuropsychiatric Research Laboratory (CNRLab) is part of the Division of Cognitiv...e Neuroscience within the Department of Neurology at the Johns Hopkins University School of Medicine. Its current projects include investigating the motor system's contribution to cognitive function; HIV-related neuroplasticity and attention-to-reward as predictors of real world function; and brain function and cognition in Lyme disease. view more

Dr. Raul Chavez-Valdez is an assistant professor in the Department of Pediatrics with great int...erest in the mechanisms of delayed injury and repair/regeneration in the developing neonatal brain following injury, specifically following hypoxic-ischemic encephalopathy (birth asphyxia). He collaborates with Dr. Frances Northington (Pediatrics) and Dr. Lee Martin (Pathology/Neuroscience) in unveiling the importance of programmed necrosis in the setting of brain injury induced by birth asphyxia. He is especially interested in the role of brain derived neurotrophic factor and neurotrophin-4 following birth asphyxia and the changes that may explain the suspected excitatory/ inhibitory (E/I) imbalance particularly in the hippocampus. His work is highly translational since delayed hippocampal injury due to E/I imbalance may explain memory deficits observed despite therapeutic hypothermia in neonates suffering birth asphyxia. All of these aspects of developmental neuroplasticity are the base of his Career Development Award (NIH/NINDS-K08 award) and applications to other agencies. Additionally, he is part of multiple clinical efforts as part of the Neuroscience Intensive Care Nursery (NICN). He has been a Sutland-Pakula Endowed Fellow of Neonatal Research since September 2013. view more
