Fig. 4.
Left column: two different rotational motion stimuli. Right column: the corresponding change in firing rate in response to the stimuli. The time (T threshold) it takes for the firing rate to overcome sensory threshold (1 unit of the firing rate) can be found (see inset) given the transfer functions of the sensors. Upper and lower row show the differences between a trapezoidal (condition VI) and a triangular (condition V) acceleration profile
