This study examines the spinocerebellar locations of Purkinje cells that responded to passive foot rotations at the ankle joint in anaesthetized cats. Using a novel approach for mapping the locations of recorded cells from several animals onto an unfolded two-dimensional representation of the cortex, we found that cells distributed throughout the anterior-posterior extent of the spinocerebellar cortex, except in the most medial parts corresponding to zones a and b, were responsive to ankle joint rotation. The cell distributions revealed a clustering according to their response amplitudes, which showed evidence for both parasagittal and transverse banding.
