First centered on the premotor cortex, our studies have evolved with time
towards investigation of its connectivity, namely with the posterior parietal
cortex, as well as comparing premotor neuronal activity to that of prefrontal
cortex and basal ganglia. Having identified the pathways which may mediate
parallel visuo-motor channels, we have developped projects to study the kinematics
of reaching and grasping in non human primates in order to compare with human
data. In parallel, physiological experiments in human subjects allow us to
ask the question of how and when do frontal and parietal cortical areas interact
during visuo-motor tasks. On the other hand, our findings that neuronal activity
within the premotor cortex, prefrontal cortex and basal ganglia (namely the
striatum) reflects different but complementary aspects of visuo-motor processing,
we now study the evolution of activity during learning.
Recently, collaborative studies with the fMRI group of Christoph Segebarth
(INSERM U438, Grenoble) allow us to conduct parallel experiments on healthy
human volunteers, namely within the scope of (a) attention
vs. intention, and (b) visuo-motor learning.
