The control of the many degrees of freedom of the hand through func- tional modules (hand synergies) has been proposed as a potentially useful model to describe how the hand can maintain postures while being able to rapidly change its configuration to accomplish a wide range of tasks. However, whether and to what extent synergies are actually encoded in motor cortical areas is still debated.Adirect encoding of hand synergies is suggested by electrophysiological studies in nonhu- man primates, but the evidence in humans resulted, so far, partial and indirect. In this chapter,we reviewthe organization of the brain network that controls hand posture in humans and present preliminary results of a functional Magnetic Resonance Imaging (fMRI) on the encoding of synergies at a cortical level to control hand posture in humans.
