FIG. 3.

Transient-type auditory frequency sensitive saccular afferent neurons phase lock action potentials with packets of pulsed LiFU. (A) 1 ms packets pLiFU repeated at 10 pps evoked phase-locked action potential discharge with ISIs (blue dots) at winding ratios of k = 1–6 (dashed lines). Winding ratios approached 1 (one action potential per pulse) as the stimulus strength (reported as preamplifier voltage here 0.15–1 V) was increased. (B) Saccular afferent exhibiting adaptation to 1 ms packets of pLiFU at 80 pps with winding ratios initially at k = 1 and 2, running down during the stimulus to winding ratios of 2 and 3. Both of these saccular afferent neurons (A), (B) were silent at rest.
