Cognitive Motor Control

Our team integrates neurophysiological, behavioral and computational approaches to understand how cortical and spinal processes represent internal goals, predictions, learning mechanisms and contextual constraints, and how they are translated into motor plans and behaviors.
We do similar experiments in human and monkeys and assess various motor behaviors in terms of the dynamics of multi-joint arm reaches and object-related hand movements. In monkeys we record massively parallel single neuron activities and local field potentials (LFP) as well as intracranial EEG in various cortical areas.

In humans we use neuroimaging (fMRI), transcranial magnetic stimulation (TMS), and neurophysiological techniques to record brain activity (EEG, MEG, intracranial EEG) and muscular activity (EMG, single motor unit activity) to investigate cognitive motor control processes.

Our experiments are interpreted in the framework of computational motor control and neuronal coding theories.

The design of such parallel studies is a novel approach, which should result in a cross-fertilization of ideas. The study of the sensorimotor transformations from intention to action via planning is both an interpretable window into the operation of the cerebral cortex and an essential pre-requisite to progress in brain machine interface (BMI) technology and neuro-rehabilitation, especially in hemiplegic patients.
