Work History

research associate

McGill University Faculty of Medicine

From August 2013

This self-motion is sensed by the vestibular system, which contributes to an impressive range of brain functions, from the most automatic reflexes to spatial perception and motor coordination. Our studies investigate the sensorimotor transformations required for the control of movement, by tracing the coding of vestibular stimuli from peripheral afferents, to behaviorally-contingent responses in central pathways, to the readout of accurate perception and behavior.

I developed one novel neurophysiological recording under outside environment in freely moving monkeys when I got Master Degree from 2005-2006. We used telemetric technique to transmit the data of extracellular single units and video of eye movement to the receiver at the same time. This research methods was published in Journal of Neuroscience Methods(35(2006) 35–41) and Methods(38 (2006) 202–209)The technique was commented ” It is one great progress to study the primate neuronal activity and behaviour” by Methods reviewers. In addition, we developed one new maze model to study spatial learning and memory in freely moving monkeys, which is considered as one perfect model to study the egocentric and allocentric coordinate system in freely monkeys. In addition, using manganese-enhanced magnetic resonance imaging (MEMRI) and traditional electroencephalograph recording(Gamma band) techniques in rats, I studied the dynamic changes in orbitofrontal cortex during morphine administration and withdrawal. Then our data was published in Neuroscience( 138 (2006) 77–82). This is my first article published as first author, which gave me confidence in research.
As a postdoc fellow in University of Western Ontario,Using a conditioned place preference procedure combined with in vivo multi-unit recording procedures, I am able to expertly and quickly establish this extremely complex and difficult neuroscience research procedure. Through the diligent efforts , we now have a fully operational system for in vivo recording of neuronal populations during various, long-term behavioural neuroscience experimental procedures. Indeed, my technique was the very first demonstration of long-term neuronal recording during an extended place conditioning procedure reported in the neuroscience literature.
I made several remarkable discoveries while working in Dr. Steve Laviolette’s laboratory. First, I demonstrated for the first time, that populations of neurons in the mammalian prelimbic cortex are f
