Functional expression of α7-nicotinic acetylcholine receptors by muscle afferent neurons.

abstract：:Recently developed computational techniques have been used to reduce muscle activation patterns of high complexity to a simple synergy organization and to bring new insights to the long-standing degrees of freedom problem in motor control. We used a nonnegative factorization approach to identify muscle synergies durin...
