Abstract In the present study, the sensitivity to sinusoi-
dal linear accelerations in the plane of the utricular mac-
ula was tested in afferents. The head orientation relative
to the translation axis was varied in order to determine
the head position that elicited the maximal and minimal
responses for each afferent. The response gain and phase
values obtained to 0.5-Hz and 2-Hz linear acceleration
stimuli were then plotted as a function of head orientation
and a modified cosine function was fit to the data. From
the best-fit cosine function, the predicted head orienta-
tions that would produce the maximal and minimal re-
