Topography and receptive field organization of the body midline representation in the ventrobasal complex of the cat.

abstract：:Joint stiffness measurements during small transient perturbations have suggested that stiffness during movement is different from that observed during posture. These observations are problematic for theories like the classical equilibrium point hypothesis, which suggest that desired trajectories during movement are en...
