Abstract. Quantitative study of the static and dynamic
response properties of some otolith-sensitive neurons
has been difficult in the past partly because their re-
sponsesto different linear accelerationvectors exhibited
no "null" plane and a dependenceof phase on stimulus
orientation. The theoretical formulation of the response
ellipse provides a quantitative way to estimate the spa-
tio-temporal properties of such neurons. Its semi-major
axis gives the direction of the polarrzation vector (i.e.,
