Preferred axis of rotation of floccular Purkinje cells in the decerebrate cat

Responses of 35 Purkinje cells in decerebrate cats were recorded during 0.5 Hz rotations in 4–11 vertical planes and the horizontal plane to determine their semicircular canal input. Most neurons received convergent input from two canals (21 neurons) or 3 canals (5 neurons). Few Purkinje cells were maximally sensitive to rotations about an axis appropriate to their inferior olivary input as determined by Gerrits and Voogd [15,24,27,49].
