Abstract. There exist otolith-sensitive vestibular nuclei
neurons with spatio-temporal properties that can be
described by two responsevectors that are in temporal
and spatial quadrature. These neurons respond to the
component of a stimulus vector on a plane rather than
a single axis. It is demonstrated here that these"two-di-
mensional" linear accelerometer neurons can function
as one-dimensional angular velocity detectors.The two-
dimensional property in both space and time allows
these neurons to encode the component of the stimulus
angular velocity vector that is normal to the plane
