Research in the Bakker Memory Laboratory is focused on understanding the mechanisms and brain n...etworks underlying human cognition with a specific focus on the mechanisms underlying learning and memory and the changes in memory that occur with aging and disease. We use a variety of techniques including neuropsychological assessments, experimental behavioral assessments and particularly advanced neuroimaging methods to study these questions in young and older adults and patients with mild cognitive impairment, Alzheimer’s disease, Parkinson’s disease and epilepsy.

Through our collaborations with investigators in both basic science and clinical departments, including the departments of Psychiatry and Behavioral Sciences, Psychological and Brain Sciences, Neurology and Public Health, our research also focuses on brain systems involved in spatial navigation and decision-making as well as cognitive impairment in neuropsychiatric conditions such as schizophrenia, eating disorders, obsessive-compulsive disorders, depression and anxiety. view more

Dr. Haughey directs a disease-oriented research program that address questions in basic neurobi...ology, and clinical neurology. The primary research interests of the laboratory are:

1. To identify biomarkers markers for neurodegenerative diseases including HIV-Associated Neurocognitive Disorders, Multiple Sclerosis, and Alzheimer’s disease. In these studies, blood and cerebral spinal fluid samples obtained from ongoing clinical studies are analyzed for metabolic profiles through a variety of biochemical, mass spectrometry and bioinformatic techniques. These biomarkers can then be used in the diagnosis of disease, as prognostic indicators to predict disease trajectory, or as surrogate markers to track the effectiveness of disease modifying interventions.
2. To better understand how the lipid components of neuronal, and glial membranes interact with proteins to regulate signal transduction associated with differentiation, motility, inflammatory signaling, survival, and neuronal excitability.
3. To understand how extracellular vesicles (exosomes) released from brain resident cells regulate neuronal excitability, neural network activity, and peripheral immune responses to central nervous system damage and infections.
4. To develop small molecule therapeutics that regulate lipid metabolism as a neuroprotective and restorative strategy for neurodegenerative conditions. view more

The Brain Health Program is a multidisciplinary team of faculty from the departments of neurolo...gy, psychiatry, epidemiology, and radiology lead by Leah Rubin and Jennifer Coughlin. In the hope of revealing new directions for therapies, the group studies molecular biomarkers identified from tissue and brain imaging that are associated with memory problems related to HIV infection, aging, dementia, mental illness and traumatic brain injury. The team seeks to advance policies and practices to optimize brain health in vulnerable populations while destigmatizing these brain disorders.

Current and future projects include research on: the roles of the stress response, glucocorticoids, and inflammation in conditions that affect memory and the related factors that make people protected or or vulnerable to memory decline; new mobile apps that use iPads to improve our detection of memory deficits; clinical trials looking at short-term effects of low dose hydrocortisone and randomized to 28 days of treatment; imaging brain injury and repair in NFL players to guide players and the game; and the role of inflammation in memory deterioration in healthy aging, patients with HIV, and other neurodegenerative conditions. view more

Dr. Jantzie, associate professor, received her Ph.D. in Neurochemistry from the University of A...lberta 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 neurorepair 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

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 studies of the Functional Neurosurgery Lab currently test whether neural activity related t...o 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 structures.

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 more
