The Bergles Laboratory studies synaptic physiology, with an emphasis on glutamate transporters and glial involvement in neuronal signaling. We are interested in understanding the mechanisms by which neurons and glial cells interact to support normal communication in the nervous system. The lab studies glutamate transport physiology and function. Because glutamate transporters play a critical role in glutamate homeostasis, understanding the transporters' function is relevant to numerous neurological ailments, including stroke, epilepsy, and neurodegenerative diseases like amyotrophic lateral sclerosis (ALS). Other research in the laboratory focuses on signaling between neurons and glial cells at synapses. Understanding how neurons and cells communicate, may lead to new approaches for stimulating re-myelination following injury or disease. Additional research in the lab examines how a unique form of glia-to-neuron signaling in the cochlea influences auditory system development, whether defects in cell communication lead to certain hereditary forms of hearing impairment, and if similar mechanisms are related to sound-induced tinnitus.

The Zanvyl Krieger Mind/Brain Institute is dedicated to the study of the neural mechanisms of higher brain functions using modern neurophysiological, anatomical and computational techniques. Our researchers use various approaches to understand information processing and its influence on perception, memory, abstract thought, complex behavior and consciousness. Systems and cognitive laboratories use neurophysiology, brain imaging and psychophysics to develop a quantitative, network-level understanding of cognitive information processing. Other researchers use analytical approaches such as system identification, dimensionality reduction, information theory and network modeling to understand information processing. Other areas of research in the Institute include the study of how visual and tactile information processing leads to perception and understanding of two- and three-dimensional objects. Another focus is on neural processing and recognition of speech and other complex sounds. Still other laboratories study neural mechanisms of attention, memory formation, motor learning, decision-making and executive control of behavior.

Our laboratory is interested in understanding the neural basis of auditory perception and vocal communication in a naturalistic environment. We are interested in revealing neural coding mechanisms operating in the cerebral cortex and how cortical representations of biologically important sounds emerge through development and learning.

Established in 2004, the MRB Molecular Imaging Service Center and Cancer Functional Imaging Core provides comprehensive molecular and functional imaging infrastructure to support the imaging research needs of the Johns Hopkins University faculty. Approximately 55-65 different Principal Investigators use the center annually. The MRB Molecular Imaging Service Center is located behind the barrier within the transgenic animal facility in the basement of MRB. The MRB location houses a 9.4T MRI/S scanner for magnetic resonance imaging and spectroscopy, an Olympus multiphoton microscope with in vivo imaging capability, a PET-CT scanner, a PET-SPECT scanner, and a SPECT-CT scanner for nuclear imaging, multiple optical imaging scanners including an IVIS Spectrum, and a LI COR near infrared scanner, and an ultrasound scanner. A brand new satellite facility in CRB2-LB03 opens in 2019 to house a simultaneous 7T PET-MR scanner, as well as additional imaging equipment, to meet the growing molecular and functional imaging research needs of investigators. To image with us, MRB Animal Facility training and Imaging Center Orientation are required to obtain access to the MRB Animal Facility and to the MRB Molecular Imaging Center (Suite B14). The MRB Animal Facility training group meets at 9:30 am on Thursdays at the Turner fountain/MRB elevator lobby. The Imaging Center orientation group meets at 1 pm on Thursdays at the Turner fountain, and orientation takes approximately 30 min. Please keep in mind that obtaining access to both facilities requires time, so please plan in advance.

Research interests in the Marcia Canto Lab include pancreatic neoplasms, Barrett’s esophagus and endomicroscopy. We are also interested in the use of endoscopic ultrasound to identify early-stage pancreatic cancer and its precursors.

Shelby Kutty, M.D., Ph.D., is an authority on cardiovascular imaging, including echocardiography, magnetic resonance imaging and computed tomography of congenital heart disease. His areas of academic interest have focused on myocardial function assessment, therapeutic ultrasound and cardiovascular outcomes. Kutty’s research includes developing new imaging technology applications such as a smartphone application that uses patients’ echocardiographic images to track their progress. His work gives pediatric cardiologists better ways to predict outcomes in their patients and provide the most effective and appropriate treatments.
