Partial and complete deafferentation of cat hindlimb: the contribution of behavioral substitution to recovery of motor function.

abstract：:If horizontal saccades or smooth-pursuit eye movements are made with the line-of-sight at different elevations, the three-dimensional (3D) angular rotation axis of the globe tilts by half the vertical eye eccentricity. This phenomenon is named "half-angle rule" and is a consequence of Listing's law. It was recently fo...
