We use human brain imaging in order to elucidate the brain pathophysiology that may contribute to altered feeding states in anorexia and bulimia nervosa. Currently our primary focus is on brain reward pathway function, but we also study behaviors such as anxiety that could drive unhealthy eating. During brain scanning, we use tasks based on neuronal models to activate brain circuits that may be associated with particular neurotransmitter systems in the brain and that could be manipulated behaviorally or psychopharmacologically. In addition to the functional brain response, we gather data on brain structure and genotype of relevant neurotransmitter systems and test whether they predict brain activation. Website.

Ethan Hughes, PhD Cellular Neuroscience. The long-term goals of our work are to understand how neuron-glial interactions modulate brain function and contribute to pathology in neurodegenerative disease. Towards this goal, we study the interactions of oligodendrocyte lineage cells with neurons in the adult cerebral cortex. Oligodendrocytes are the myelin-forming cells of CNS and their ensheathment of axons is essential for rapid synaptic communication. Oligodendrocyte dysfunction results in a diverse group of pediatric and adult disorders, most notably, X-linked adrenoleukodystrophy and multiple sclerosis. However, our understanding of the functions of oligodendrocytes and their precursors remains in its infancy. We use advanced imaging and cell-specific genetic manipulations to explore dynamic changes in neurons and glial cells in the living adult brain using long-term multi-photon in vivo imaging, optogenetics, genetically encoded calcium indicators, and transcriptomics.

Amanda J. Law, MSc. PhD. Psychiatry Psychiatric, Neurodevelopmental, and Behavioral Disorders. My research focuses on understanding the molecular and cellular mechanisms of genetic susceptibility to severe psychiatric disorders, including schizophrenia, translating this at the level of brain development and behavior. Using a multidisciplinary basic neuroscience approach my research incorporates: human postmortem studies of the adult and fetal brain, primary human cell models, rodent primary neuronal culture, transgenic animal models, clinical genetics and pharmacological studies. Our work is highly translational and employs state-of-the-art molecular and cell biology techniques (e.g. quantitative real-time PCR, in-situ hybridization, recombinant DNA technology, lentiviral technology, primary hippocampal, striatal and cortical culture and proteomic studies) combined with comprehensive behavioral, anatomical and neurophysiological studies in transgenic rodents to determine the role of susceptibility genes in early brain development and adult brain function. In the past years, my research has focused on a key neurodevelopmental pathway; the neuregulin (NRG1/NRG3)-ErbB4-phosphoinositide 3-kinase (PI3K)-AKT gene network, as it relates to genetic risk for schizophrenia and related disorders. This work has recently expanded to include examination of a number of closely interacting genes and pathways, including Neurexin 1 (NRXN1), AKT2, AKT3 and mTOR, all of which have been strongly implicated in neurodevelopmental disorders including autism, schizophrenia and bipolar disorder.

Hunting Potter, PhD Alzheimer�s disease and cognitive disorders. Our current research is devoted to laboratory and clinical investigation of neurodegenerative diseases, particularly Alzheimer�s disease (AD) and trisomy 21/Down syndrome (DS). We use a variety of molecular, cellular and biochemical techniques in combination with in vivo behavioral studies to investigate how the Alzheimer�s amyloid beta peptide causes disruptions of cellular function and how we can prevent or reverse the toxic effects of amyloid beta. We have found aneuploid neurons and other cells in patients and mouse models of Niemann Pick C and Fronto-Temporal Dementia, and that the aneuploid cells are prone to apoptosis, suggesting that chromosome mis-segregation may underlie many different forms of neurodegeneration.

Katie Rennie, PhD. Otolaryngology. Vestibular System. Research in my laboratory is focused on hair cells of the vestibular system. The vestibular system of the inner ear senses accelerations of the head and interacts with other systems to produce the sensation of balance. It is estimated that more than one third of adults in the US experience vestibular dysfunction at some time in their life. However the mechanisms underlying normal and abnormal processing of vestibular sensory signals are not well understood. Our research aims to elucidate how signals are processed in the peripheral vestibular system using rodent models. In such models the vestibular system is immature at birth and the membrane properties of semicircular canal type I hair cells change dramatically during the first few postnatal weeks. We are investigating concurrent changes in synaptic transmission between hair cells and their afferent and efferent neurons during development. Website.

Ernesto Salcedo, PhD. Cell and Developmental Biology. Neuroanatomy and functional organization. Our research focuses on understanding how the organization of the brain helps its function. Specifically, we focus on the main olfactory bulb of mice, a highly organized structure which processes the olfactory information sent directly from the olfactory epithelium in the nose. To understand how this neural organization helps encode olfactory information, we have generated a three-dimensional reconstruction of the main olfactory bulb. We are currently working to deconstruct the activity seen in different parts of the bulb in response to different smells. With this information, we ultimately hope to link activity in the bulb to olfactory-driven behavior, such as predator detection or mate selection. Our methodology includes brain dissection, immunohistochemical (antibodies) labeling techniques, microscopy and digital imaging, and computer programming. Website.
Kalynn M. Schulz Ph.D. Developmental Behavioral Neuroscience. Our laboratory studies the neural mechanisms by which developmental stress exposure causes adult behavioral dysfunction. Several neuropsychiatric illnesses (e.g. schizophrenia and depression) are associated with stress exposure during development. Using rodent models, we are investigating the impact of stress hormones (e.g. corticosterone) during different developmental stages on hippocampal development, and in particular, the development of nicotinic acetylcholine receptors in the hippocampus. As such, we are currently testing the hypothesis that stress-induced changes in hippocampal nicotinic receptor function underlies the deleterious behavioral consequences of developmental stress exposure. email.

Cristin Welle, PhD Brain Interfaces. Advances in neurotechnology are transforming how we learn about, and interact with, our own nervous systems. The BIOElectrics Lab utilizes advanced neuroscience research tools to explore the intersection between technology and brain. Our goals are to provide new insights into the key factors that make neural interface devices effective, and to use cutting-edge neural technology to learn more about the way our nervous systems function. We are using chronic electrophysiology, optogenetics, volumetric tissue clearing, and in vivo two-photon imaging in animal models to measure the biological responses to implanted neurotechnology, and the plasticity in neural circuits resulting from device interventions. Specific research projects focus on how high-density electrode arrays in cortex effect the glymphatic network, the neuroinflammatory response and subsequent neural function. In addition, we�re exploring how stimulation of the peripheral nervous system can induce plasticity in the motor cortex. We plan to apply these insights to the development of new neural interface devices that bring benefit to patients. Medical devices that interact with the nervous system already bring enormous therapeutic benefit to patients with diseases such as Parkinson’s, epilepsy, depression, obsessive compulsive disorder, and are under investigation for many more neurologic conditions.

Xiaoli Yu, PhD. Neurology. Neuroimmunology. My research investigates the specificity of IgG in patients with multiple sclerosis (MS) using phage-displayed peptide libraries approach. A hallmark of MS is the persistence of oligoclonal IgG and elevated numbers of B cells in the CNS. Our published studies have demonstrated the antigen-driven response of clonally expanded B cells in MS. We are using recombinant antibodies generated from these B cells to identify peptide epitopes/mimotopes by panning phage-displayed random peptide libraries. The specificity of the peptides is confirmed by ELISA, immunoblot and competitive inhibition assays. By applying a highly sensitive phage mediated immuno-PCR technique, these peptides are screened for bindings to IgG in multiple MS patients. MS peptides can then be used to determine the corresponding protein antigens using bioinformatics approach. Identification of MS antigens has the potential to determine the cause of disease, and to develop strategies for diagnostic and therapeutic intervention. Website.
