Dr. Jantzie, associate professor, received her Ph.D. in Neurochemistry from the University of Alberta in 2008. In 2013 she completed her postdoctoral fellowship in the Department of Neurology at Boston Children's Hospital & Harvard Medical School and became faculty at the University of New Mexico. Dr. Jantzie then joined the faculty Departments of Pediatrics (Neonatal-Perinatal Medicine) and Neurology at Johns Hopkins University and the Kennedy Krieger Institute in January 2019. Her lab investigates the pathophysiology of encephalopathy of prematurity, and pediatric brain injury common to infants and toddlers. Dr. Jantzie is dedicated to understanding disease processes in the developing brain as a means to identifying new therapeutic strategies and treatment targets for perinatal brain injury. Her lab studies neural substrates of cognition and executive function, inhibitory circuit formation, the role of an abnormal intrauterine environment on brain development, mechanisms of neurorepa...ir and microglial activation and polarization. Using a diverse array of clinically relevant techniques such as MRI, cognitive assessment, and biomarker discovery, combined with traditional molecular and cellular biology, the Jantzie lab is on the front lines of translational pediatric neuroscience.? view more
Johns Hopkins Neuromyelitis Optica (NMO) Clinic
The Johns Hopkins NMO Clinic launched in July 2009 and now follows 210 patients with NMO or NMO Spectrum Disorder (last count March 31, 2014), along with 81 patients with idiopathic transverse myelitis, 45 patients with recurrent transverse myeltis and small handful with recurrent optic neuritis. We also follow a few patients with multiple sclerosis who thought they might have NMO.
Until 2005, 90% of NMO patients were misdiagnosed as multiple sclerosis and treated with medications that did not help. We've become much better at identifying NMO and treating it correctly. Whereas 30% of patients used to be blind or paralyzed within 5 years of diagnosis, now > 70% of our patients are remission without any progression of disease using safe medications.
Dr. Michael Levy directs the NMO Clinic and sees NMO patients in clinic every other Monday. He completed the MD/PhD program at Baylor College of Medicine in Houston, TX (where he grew up), and trained in the neurology residency and fe...llowship programs at Johns Hopkins before joining the faculty in 2009. In addition seeing patients with NMO, Dr. Levy also runs clinical trials in NMO (see the clinical trials page) and runs a basic science laboratory devoted to the finding the cure to NMO.
Maureen Mealy, RN, is the program director for the Johns Hopkins Transverse Myelitis Center and the NMO Clinic. Maureen graduated from the University of Maryland and obtained her nursing degree from the Johns Hopkins School of Nursing. She has 7 years of experience in neurocritical care nursing and 6 years of experience working with patients with NMO.
Regina Brock-Simmons, RN, is the clinical coordinator for all of the trials in NMO. While Regina is relatively new to NMO, she has 10 years of experience running clinical trials at Johns Hopkins and is also trained in phlebotomy and infusions. view more
Karen Bandeen-Roche Lab
The Karen Bandeen-Roche Lab explores the application of underlying variable methods in epidemiologic and psychosocial research. Our team seeks to improve the ability to measure key outcomes like functional status and psychological disorders. Our other areas of statistical research include the study of classification and variance structure and multivariate survival analysis. We are deeply invested in the field of gerontology as well as ophthalmology and neurology.
We started Kata to bridge the gap between professional experiential production and neuroscience, clinical neurology, and medical hardware. We strive to build experiences and technology from the ground up, with a focus on mission, and at a level that is consistent with the best productions in the industry. We mirror the thousands of hours that go into a level design in a video game, but with the crucial difference that the focus is on the subtleties required for patient treatment or wellness. Our designs require high-frequency iterative development with patients and users in countless game-play sessions in which they provide crucial feedback. Characters have been painstakingly crafted to elicit profound emotional responses. Some of the requirements for patients or the elderly population in this space are qualitatively different from what is needed in the entertainment marketplace. That said we have also understood the critical artistic similarities.
The core ethos of Kata is that the... challenge of complex movement has profound benefits for cognition, wellness, and brain repair. Specifically, there is growing evidence that complex motor movement can have cognitive benefits that go beyond what has been reported for exercise alone. When designing experiences to treat motor impairments after stroke, maximizing rigorous and dynamic motor input is a requirement. New interactive technologies will allow people to engage in diverse and complex motor movements, even in the home, which was previously impossible.
Overall it has been a very exciting journey, combining art, medicine, technology, and neuroscience. We continue to build, discover, and craft immersive experiences, side by side with physicians, physical therapists, and scientists, with the common goal of pushing clinical care and wellness forward. We believe this is only possible by having a mission focused design group embedded in an academic hospital. Ultimately, we wish to scale and perfect these innovations into other hospitals. Kata is a true hybrid of academia, and industry, doing what neither can do in isolation. We hope the ethos and design philosophy behind Kata provides the impetus for its expansion, partnerships, and growth. view more
The Cognitive Neuropsychiatric Research Laboratory (CNRLab) is part of the Division of Cognitive 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.
Michael Wolfgang Laboratory
The Wolfgang Laboratory is interested in understanding the metabolic properties of neurons and glia at a mechanistic level in situ. Some of the most interesting, enigmatic and understudied cells in metabolic biochemistry are those of the nervous system. Defects in these pathways can lead to devastating neurological disease. Conversely, altering the metabolic properties of the nervous system can have surprisingly beneficial effects on the progression of some diseases. However, the mechanisms of these interactions are largely unknown.
We use biochemical and molecular genetic techniques to study the molecular mechanisms that the nervous system uses to sense and respond to metabolic cues. We seek to understand the neurometabolic regulation of behavior and physiology in obesity, diabetes and neurological disease.
Current areas of study include deconstructing neurometabolic pathways to understand the biochemistry of the nervous system and how these metabolic pathways impact animal beh...avior and physiology, metabolic heterogeneity and the evolution of metabolic adaptation. view more
The Calabresi Lab is located in the department of Neurology at the Johns Hopkins University School of Medicine. Our group investigates why remyelination occasionally fails following central nervous system demyelination in diseases like multiple sclerosis. Our primary focus is on discovering the role of t-cells in promoting or inhibiting myelination by the endogenous glial cells.
The studies of the Functional Neurosurgery Lab currently test whether neural activity related to the experimental vigilance and conditioned expectation toward pain can be described by interrelated networks in the brain. These two psychological dimensions play an important role in chronic pain syndromes, but their neuroscience is poorly understood. Our studies of spike trains and LFPs utilize an anatomically focused platform with high temporal resolution, which complements fMRI studies surveying the whole brain at lower resolution. This platform to analyze the oscillatory power of structures in the brain, and functional connections (interactions and synchrony and causal interactions) between these structures based upon signals recorded directly from the waking human brain during surgery for epilepsy and movement disorders, e.g. tremor. Our studies have demonstrated that behaviors related to vigilance and expectation are related to electrical signals from the cortex and subcortical struc...tures.
These projects are based upon the combined expertise of Dr. Nathan Crone in recordings and clinical management of the patients studied; Dr. Anna Korzeniewska in the analyses of signals recorded from the brain; Drs. Claudia Campbell, Luana Colloca and Rick Gracely in the clinical psychology and cognitive neurology of the expectation of pain and chronic pain; Dr. Joel Greenspan in quantitative sensory testing; and Dr. Martin Lindquist in the statistical techniques. Dr. Lenz has conducted studies of this type for more than thirty years with continuous NIH funding. view less
Epilepsy affects 1-3% of the population and can have a profound impact on general health, employment and quality of life. Medial temporal lobe epilepsy (MTLE) develops in some patients following head injury or repeated febrile seizures. Those affected may first suffer spontaneous seizures many years after the initial insult, indicating that the neural circuit undergoes a slow pathologic remodeling over the interim. There are currently no methods of preventing the development of MTLE. It is our goal to better understand the process in order to slow, halt, and ultimately reverse it.
Our laboratory draws on electrophysiology, molecular biology, and morphology to study the contribution of dysregulated neurogenesis and newborn neuron connectivity to the development of MTLE. We build on basic research in stem cell biology, hippocampal development, and synaptic plasticity. We work closely with colleagues in the Institute for Cell Engineering, Neurology, Neurosurgery, Biomedical Engineering..., and Radiology. As physician neuropathologists our grounding is in tissue alterations underlying human neurologic disease; using human iPSC-derived neurons and surgical specimens we focus on the pathophysiological processes as they occur in patients.
By understanding changes in cell populations and morphologies that affect the circuit, and identifying pathologic alterations in gene expression that lead to the cell-level abnormalities, we hope to find treatment targets that can prevent the remodeling and break the feedback loop of abnormal activity > circuit change > abnormal activity. view more
