Motor adaptation and plasticity of hand-grasping signals in the macaque
The reciprocally connected premotor and parietal cortical regions F5 and AIP play an important role in planning and performing hand-grasping movements of behaving primates, because the transformation of visual information into motor plans takes place there. While the trained animals perform hand grasping movements, we will record neural activity in these regions using permanently implanted
multi-electrodes. Analysing this neural data (spiking activity & local field potentials) from several simultaneously recorded channels will lead to new information about the interactions of neurons within and in between the two regions. In a second effort, we will then decode the grasping intentions of the animals online by statistical classification and perturbe the decoded signals during online-feedback experiments. This will provide valuable insights into motor adaptation and plasticity in the primate hand grasping system.
