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.

"A cholinergic explanation of dense amnesia?"
Mark G. 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.
