Cerebral response to pyramidal tract stimulation in wood rats and its relation to laboratory rats.

abstract：:It has long been assumed that the human central nervous system uses flexible combinations of several muscle synergies to effortlessly and efficiently control redundant movements. However, whether muscle synergies exist in the neural circuit remains controversial, and it is critical to examine the association between t...
