Abstract:
Sensorimotor control of movement, posture and force in Human: Insights from deafferented patients’ strategies
Movement is key in life. Correct execution of movement allows us to
reach what is desired, the targeted object for instance. This
translates in incredible performances, and substantial incomes, for
professional athletes, as seen in soccer competitions and the Olympics.
In this talk, I will present evidence of the importance of
somatosensory signals for motor control and learning, based on
observations of rare individuals with a massive yet specific
somatosensory loss. Such loss resulted from a severe sensory
neuropathy. I will then present studies of short-term adaptation to a
new limb dynamics. The fact that patients deprived of somatosensory
feedback can use vision to adapt as well as healthy individuals
highlights the ability of the nervous system to use error signals from
a single sensory modality to fine tune motor commands on a
trial-by-trial basis.
