The Lau Lab uses a combination of computational and experimental approaches to study the atomic... and molecular details governing the function of protein complexes involved in intercellular communication. We study ionotropic glutamate receptors (iGluRs), which are ligand-gated ion channels that mediate the majority of excitatory synaptic transmission in the central nervous system. iGluRs are important in synaptic plasticity, which underlies learning and memory. Receptor dysfunction has been implicated in a number of neurological disorders.
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
The David Linden Laboratory has used both electrode and optical recording in cerebellar slice a...nd culture model systems to explore the molecular requirements for induction and expression of these phenomena. Along the way, we discovered a new form of plasticity. In addition, we have expanded our analysis to include use-dependent synaptic and non-synaptic plasticity in the cerebellar output structure, the deep nuclei.
Our investigations are central to understanding the cellular substrates of information storage in a brain area where the behavioral relevance of the inputs and outputs is unusually well defined. In addition, our investigations have potential clinical relevance for cerebellar motor disorders and for disorders of learning and memory generally. view more
Research in the Diane Griffin Lab focuses on the viral, cellular and immunologic determinants o...f diseases caused by alphaviruses and the measles virus. Our current studies aim to understand the immune-system mechanisms behind viral clearance and disease enhancement. Our team is also working to understand the pathogenesis of the measles virus, with a focus on developing new vaccines and learning how the virus induces immunosuppression.view more
The Human Brain Physiology and Stimulation Laboratory studies the mechanisms of motor learning...and develops interventions to modulate motor function in humans. The goal is to understand how the central nervous system controls and learns to perform motor actions in healthy individuals and in patients with neurological diseases such as stroke. Using this knowledge, we aim to develop strategies to enhance motor function in neurological patients.
To accomplish these interests, we use different forms of non-invasive brain stimulation techniques, such as transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), as well as functional MRI and behavioral tasks. view more
Research in the Laboratory of Auditory Neurophysiology aims to understand brain mechanism respo...nsible for auditory perception and vocal communication in a naturalistic environment. We are interested in revealing neural mechanisms operating in the cerebral cortex and how cortical representations of biologically important sounds emerge through development and learning.
We use a combination of state-of-the-art neurophysiological techniques and sophisticated computational and engineering tools to tackle our research questions.
Current research in our laboratory includes the following areas (1) neural basis of auditory perception, (2) neural mechanisms for vocal communication and social interaction, and (3) cortical processing of cochlear implant stimulation.view more
The Laboratory of Vestibular NeuroAdaptation investigates mechanisms of gaze stability in peopl...e with loss of vestibular sensation. A bulk of our research investigates motor learning in the vestibulo-ocular reflex (VOR) using different types of error signals. In addition, we investigate the synergistic relationship between the vestibular and saccadic oculomotor systems as trainable strategies for gaze stability. We are particularly interested in developing novel technologies to assess and deliver improved rehabilitation outcomes. We are validating a hand-held computer tablet for assessment of sensorimotor function and participating in a clinical trial comparing traditional vestibular rehabilitation against a device developed in our laboratory that can unilaterally or bilaterally strengthen the VOR.
Members of the lab include physical therapists, physicians, engineers, statisticians and post-doctoral fellows. The laboratory is supported by generous grant funding from NASA, the NIH, the DOD and grateful patients view more
