| Abstract: | Summary The subjective visual vertical (SV) has been investigated in centrifugation experiments in order to test the hypothesis, that changes in the SV are proportional to changes in the shear force acting on the utricles. The results deviate from those predicted from the  shear hypothesis. This deviation can be accounted for by assuming that the SV is determined by the average of utricular and somaesthetic inputs.Thanks are due to A. Stein for performing some of the experiments of series d and e. N.J. Wade was supported by a Forschungsstipendium from the Alexander von Humboldt-Stiftung. Renate Alton skillfully assisted with the drawings. |
