DND Visiting Speaker - Dr. Sean Mulligan http://www.sbrc.ca/content/view/926/593/ DATE: Friday, June 17th, 2011 TIME: 1:00 pm LOCATION: Room 431 Basic Medical Sciences Bldg. (Physiology Conference Room) Dr. Sean Mulligan <http://www.medicine.usask.ca/physiology/people/faculty-members/sean-mulliga…> Assistant Professor, Department of Physiology University of Saskatchewan TOPIC: Functional optical imaging in free nerve endings: a pain in the dura. Biosketch: Dr. Sean Mulligan Assistant Professor, Department of Physiology Neural Systems & Plasticity Research Group, College of Medicine, University of Saskatchewan Postdoctoral Fellow (Psychiatry) Faculty of Medicine, University of British Columbia Ph.D. (Neuroscience) Faculty of Medicine, University of Calgary M.Sc. (Biology/Neurobiology) Simon Fraser University B.Sc. (Kinesiology/Anatomy & Physiology) Simon Fraser University Teaching Interests Neuroscience Cellular and Systems Level Physiology Research Interests Pain sensitivity within the skull is restricted to the intracranial meninges, the system of membranes that envelops the brain. Afferent thinly myelinated A��-fibres and unmyelinated C-fibres that originate from the trigeminal ganglion densely innervate the meninges, in particular the cranial dura mater. It is widely recognized that activation or sensitization of these dural nociceptive afferents is responsible for the genesis of migraine headaches. However, any details of the pathophysiological mechanisms involved are largely speculative and remain to be discovered. Identification of the underlying mechanisms of activation of dural nociceptors may have important implications for understanding and mitigating the pathogenesis of migraine headaches. We have developed a novel en bloc dural-skull preparation that allows us for the first time to apply optical imaging techniques to directly study with high resolution the free nerve endings and terminals of the nociceptive fibres that terminate in the dura mater. The objective of our research is to gain insight into the neurophysiology of peripheral pain activation to better understand the pathophysiological processes that occur during migraine headache. It is our hope that this will lead to new peripheral drug targets and offer additional therapeutic treatments for this devastating illness. Laboratory Techniques We are primarily an optical imaging laboratory that uses both two-photon laser scanning imaging as well as widefield epifluorescence microscopy. Microscopes are configured for both microfluorometric and transmitted light imaging using photomultiplier tube or high sensitivity EMCCD camera based detection. We combine optical imaging of calcium signaling selectively within individual terminals with electrophysiological stimulation, pharmacological manipulations, and UV and two-photon photolysis of caged compounds.

Date: Friday, June 3, 2011 Time: 12:00 PM - 1:00 PM Location: Theatre C Dr. Michael Kawaja Professor, Department of Anatomy and Cell Biology Queen's University at Kingston Topic: Nerve Growth Factor - The driving force behind sympathetic sprouting. Biosketch: Dr. Kawaja did his undergraduate studies in biology at Acadia University and completed his doctoral degree in Anatomy at the University of Western Ontario in 1989. He then went on to have two MRC-funded post-doctoral positions, the first with Dr. Fred Gage at the University of California San Diego, and the second with Dr. John Roder at the Samuel Lunenfeld Institute at the Mount Sinai Hospital in Toronto. In 1993 Dr. Kawaja commenced his MRC-funded scholarship position as an Assistant Professor in the Department of Anatomy and Cell Biology at Queen's University. Over the last 17 years he has risen through the ranks of Associate and Full Professor at Queen's. Dr. Kawaja has held numerous operating grants from CIHR (MRC), Heart and Stroke Foundation, Ontario Neurotrauma Foundation, and Ontario Mental Ontario Ministry for Research and Innovation. He has served as a panel member of CIHR Scholarships and continues to serve as a panel member for CIHR Neuroscience "B". He has also served on a number of peer review panels including those for Alzheimer Society of Canada, Heart and Stroke Foundation of Canada, Multiple Sclerosis Society of Canada, Ontario Mental Health Foundation, and Ontario Ministry of Research and Innovation Early Researcher Awards. health Foundation. His research focuses on gaining a greater understanding of the reparative mechanisms in the mammalian central and peripheral nervous systems, as a consequence of injury and disease.
