SPATIAL-ORGANIZATION OF PROPRIOCEPTION IN THE CAT SPINOCEREBELLUM - PURKINJE-CELL RESPONSES TO PASSIVE FOOT ROTATION

This study examines the spinocerebellar locations of Purkinje cells th at responded to passive foot rotations at the ankle joint in anaesthet ized cats, Using a novel approach for mapping the locations of recorde d cells from several animals onto an unfolded two-dimensional represen tation of the cortex, we found that cells distributed throughout the a nterior-posterior extent of the spinocerebellar cortex, except in the most medial parts corresponding to zones a and b, were responsive to a nkle joint rotation. The cell distributions revealed a clustering acco rding to their response amplitudes, which showed evidence for both par asagittal and transverse banding.
