Reminder tomorrow: MNN MEETING Dr. Brent Fedirchuk
by Winnipeg Chapter Society for Neuroscience 29 Sep '11

29 Sep '11

Dr. Brent Fedirchuk Associate Professor, Department of Physiology University of Manitoba Friday, September 30th, 2011 9:00 - 10:00am PX 236/238 Psychiatry Bldg. Bannatyne Campus Topic: The facilitation of motor output by the regulation of spinal motoneuron excitability. Summary of Research: Dr. Brent Fedirchuk's Summary of Research: * Dr. Fedirchuk's research is aimed at determining the factors regulating the excitability of spinal neurons and determining how this regulation contributes to the production of useful motor output, such as locomotion. Using single-cell electrophysiological recording techniques coupled with experimental preparations able to exhibit complex motor activity, Dr. Fedirchuk and colleagues have been able to demonstrate a rapid and reversible enhancement of the excitability of spinal neurons from descending and intrinsic spinal systems. * Dr. Fedirchuk is a native Manitoban, and received a B.Sc. (Hons) in Zoology from the University of Manitoba, followed by M.Sc. and Ph.D. degrees working with Dr. Susan Shefchyk in the Department of Physiology (University of Manitoba). Dr. Fedirchuk then undertook postdoctoral training (CIHR Fellowship) with Dr. Hans Hultborn (Copenhagen) and Dr. Michael O'Donovan (NIH). Dr. Fedirchuk was recruited back to Winnipeg, initially as a Research Associate in Dr. Larry Jordan's laboratory, and subsequently as an Assistant Professor. Dr. Fedirchuk is currently an Associate Professor in the Department of Physiology, University of Manitoba. Location: PX236/238 Psychiatry Bldg.

Baxter Associate Professor Department of Neuroscience, Mount Sinai School of Medicine Abstract: Episodic memory depends on a network of interconnected brain structures. Damage to either the fornix or mammillary bodies causes amnesia in both humans and nonhuman primates. We have found that the severity of amnesia after damage to either of these structures is modulated by prior loss of cholinergic projections to the inferotemporal cortex, the cortical region through which visual information reaches these structures. Macaque monkeys with cholinergic depletion of inferotemporal cortex had unimpaired episodic memory performance. However, these monkeys were substantially more impaired following additional lesions of either the fornix or the mammillary bodies than were monkeys with intact temporal cortical cholinergic input. Reversing the order of the lesions resulted in less severe amnesia, indicating that the presence of cholinergic projections to temporal cortex at the time of fornix or mammillary body damage facilitates recovery. These findings show that humans with loss of cortical cholinergic function, for example in Alzheimer's disease, may be less able to adapt to the impairments caused by neuronal damage within cortical and subcortical structures important for memory. Consequently, drugs that increase cortical cholinergic neurotransmission may slow disease progress by augmenting this adaptive process.

(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.
