Whom am I ?
Dr. Perrey's research is concerned with the neurophysiological approach to problems of muscle fatigue
and locomotion. Prof. Perrey is the author of more than 120 publications in peer-review journals, and more than 150 scientific communications in proceedings. He is honorary member of
Institut Universitaire de France.
My centres of interests
My current researches are in the centre of issues, which have for objectives to identify, quantify and explain mechanisms responsible for changes of the motor function in humans.
Methodologies involve a state-of-the-art laboratory research to investigate neuromechanics of human movement (force, kinematics, electrophysiological signals) as well as to explore energetic metabolism adjustment to motor tasks (alveolar oxygen uptake, tissue oxygenation, NMR).
During the last years, experimental findings allow to show the importance of the central motor output in determining voluntary (loco)motor performance (for local and whole-body exercises) with and without physical or cognitive fatigue.
Functional investigation of the brain function in situ was more recently developed with electrophysiological and near-infrared spectroscopy signals. The latter enables to study brain function in everyday situations, which involve free movement of subjects.
Most recent researches integrate a multidisciplinary field on the exploration of the neural substrates underlying cognitive and motor functions in humans. They focus on the neural underpinnings of the sensory-motor (dys)functions associated with attention decrement and the possible applicability of the NIRS technique within passive BCI.
Modulating by using external stimulation methods -while measuring simultaneously- the neural activity is also investigated to facilitate the BCI control motor.
