Research Faculty and Post Doctoral Fellows

Paul Buckmaster, DVM, PhD, Professor of Comparative Medicine and Neurology & Neurological Sciences received his DVM from the University of California at Davis and a PhD from the Department of Physiology & Biophysics at the University of Washington. He was a postdoctoral fellow at the University of Washington, Colorado State University, and the University of California at Davis. He studies the pathophysiological mechanisms of epilepsy, especially temporal lobe epilepsy that is the most common type of epilepsy in adults and frequently is refractory to treatment. He uses electrophysiological and anatomical techniques to examine the neuronal circuitry of temporal lobe structures in normal and epileptic brains. He has characterized the normal electrophysiological properties and connectivity of neurons in the hilus of the dentate gyrus - the most severely altered region of the brain in temporal lobe epilepsy, and described changes in neuron subpopulations, connectivity, and functional properties in the dentate gyrus of animal models of temporal lobe epilepsy (650) 498-4774

Corinna Darian-Smith, PhD, Associate Professor of Comparative Medicine. Dr. Darian-Smith's research focuses on two main areas in her research: 1) the structural organization and function of central neural pathways (particularly of the thalamus and cortex) that underlie directed manual behavior, and 2) the capacity of these central neural pathways (circuits) to compensate/adapt following localized injury. Her laboratory uses anatomical, electro-physiological and behavioral approaches to look at the sensorimotor systems of nonhuman primates, and to examine the neural basis for functional 'recovery’ observed following the selective disruption of pathways mediating fine finger control. (650) 736-0969

Joseph Garner, DPhil, Associate Professor of Comparative Medicine. Dr. Garner's lab uses an integrated interdisciplinary approach, best described as developmental neuroethology, to address issues in human and animal well-being. The lab has a particular focus on two closely related issues: 1) Developing methods and underlying psychobiological principles to predict and prevent abnormal behavior (in animals) and mental disorder (in humans). 2) Identifying the general reasons why animal models often fail to predict human outcomes, and providing solutions to improve the efficacy and well-being of animal models. Both these issues reflect the interface between animal-based medical research, and animal well-being. The medical research community has long recognized that “good well-being is good science” – the lab’s work is directed at exploring this interface, while providing tangible deliverables for the well-being of human patients and research animals.

Shaul Hestrin, PhD, Professor of Comparative Medicine. Dr. Hestrin's group is interested in the synaptic mechanisms that underlie the coordinated activity of neurons in local cortical circuits. They are recording from multiple individual cells that are synaptically connected in neocortical slices. They have recently discovered that electrical synapses connect fast spiking (FS) cells, which are specific type of inhibitory cortical neurons. These findings raise the hypothesis that groups of cells with similar roles may synchronize their spiking activity. Current studies include: 1) Defining the cell types that are inter-connected via electrical synapses. 2) What are the specific roles of chemical and electrical synapses in coordinating spike timing within a network? 3)The role of temporal patterns of action potential trains in short- and long-term synaptic plasticity.
