Dias, Brian George
Associate Professor of Developmental Neuroscience & Neurogenetics
Our research seeks to understand not only how mammalian neurobiology, physiology and reproductive biology is impacted by psychosocial and nutritional stress but also how parental legacies of such stressors influence offspring. To achieve this understanding, we employ a lifespan approach to study how stressors affect: sperm/egg/embryo (pre-conceptional stress), the gestating fetus (in utero stress), and the developing infant (post-natal stress). Our experimental approaches include assaying learning-memory-motivation, virus-mediated manipulation of neuronal activity and gene expression, (epi)genetic profiling of cells, in vivo fiber photometry and induced pluripotent stem cells (iPSCs).
Hahn, Joel
Associate Professor (Research) of Biological Sciences
The overall goal / objective of my research is to increase scientific understanding of the fundamental structure/function relations of the nervous system. Using a variety of research methods, I have investigated neural circuits relating to specific functions (for example, neuroendocrine control of reproduction, eating, and agonistic behaviors), as well as high-level global network organization of the brain. My current research is geared mostly to developing and investigating nervous system network models, and to building tools and resources for systems neuroscience, and more recently for comparing neuroanatomical ontologies within and between species, to simplify and enable more accurate interpretation and communication of neuroscience data.
Han, S.Duke
Professor of Psychology and Family Medicine
The Han Research Laboratory is dedicated to improving the health, wellbeing, and independence of adults living into old age. We are interested in investigating the diverse factors and neurobiological mechanisms that impact cognition and decision making across the lifespan using multidisciplinary approaches informed by the fields of neuropsychology, cognitive and systems neuroscience, epidemiology, genetics, and behavioral economics.
Hires, Samuel Andrew
Associate Professor of Biological Sciences
The Hires lab is investigating the basis of biological intelligence. Over the past decade we developed numerous imaging tools to record large-scale patterns of neural activity that are used by thousands of neuroscience labs. These have resulted in hundreds of publicly available datasets embedded with rich representations of neural activity. We are now developing analytical tools, using recent AI developments, to ultimately distill undiscovered principles of biological intelligence from these datasets.
Hirsch, Judith A.
Gabilan Distinguished Professorship in Science and Engineering and Professor of Biological Sciences
Our laboratory studies the thalamus, the interface between neocortex and the sensory periphery. Thalamus was once regarded as a simple gatekeeper, passively relaying information during waking and shielding neocortex from disturbance during sleep, but this is an impoverished view. We explore how thalamus, itself, contributes to sensory integration. In particular, we study the structure of neural circuits in the visual part of thalamus, how these operate during vision and how they extract and recode information from the eye. Our work shows how thalamus might contribute to visual processing by, for example, sharpening the visual image and increasing the efficiency of the neural code. Because circuits in different parts of thalamus are similar, our work pertains to thalamic function in general.
Jakowec, Michael
Professor of Clinical Pharmacy (Teaching)
The primary focus of research in Dr. Jakowec’s laboratory is to better understand the underlying molecular mechanisms involved in neuroplasticity in the injured brain with the emphasis on the basal ganglia and prefrontal cortex, regions of the brain responsible for motor and cognitive behaviors.The overarching goal is to find improved therapeutic approaches for brain disorders especially Parkinson’s disease and drug addiction. For the past 20 years the laboratory has examined the effects of exercise on promoting neuroplasticity, particularly synaptogenesis in animal models of Parkinson’s disease. In addition to non-pharmacological approaches to promote brain repair, ongoing studies are using an experimental therapeutics approach to explore pharmacological interventions to determine if novel drugs can serve as a means to enhance brain repair, especially in the context of exercise. Recent studies have focused on the mechanisms by which astrocytes support neuronal function as well as mechanisms by which boosting mitochondrial integrity can promote improved functional connectivity and restoration of motor and cognitive behaviors.
