Orientation de la recherche
Étude des mécanismes neuronaux du cortex cérébral impliqués dans la planification et le contrôle des mouvements de pointage visuel.
Étude des mécanismes neuronaux à la base de l'apprentissage des habiletés motrices.
Principaux projets en cours:
Étude de l'activité unitaire du cortex moteur (aire 4), du cortex prémoteur (aire 6), du cortex pariétal associatif (aire 5) et du cortex
somatosensoriel (aires 3a, 3b, 1 & 2) pendant les mouvements de pointage visuel.
Étude psychophysique des mouvements du bras et de l'apprentissage des habiletés motrices chez l'homme.
Research orientation
To study the cerebral cortical neuronal mechanisms implicated in the planning and execution of visually-guided reaching movements and the neuronal mechanisms of motor skill (procedural) learning.
Current research projects:
Recordings of single-cell activity in the motor cortex (area 4), premotor cortex (area 6), parietal cortex (area 5) and somatosensory cortex (areas 3a, 3b, 1 & 2) during visually-guided reaching movements.
Psychophysical studies of arm movements and motorskill learning in humans.
