FIG. 2.
Sustained-type low frequency sensitive afferent neurons modulated firing rate in response to amplitude-modulated continuous-wave LiFU (∼0.4 equivalent “G” peak). (A) Example high-gain sustained-type utricular afferent discharge rate (ISI−1, blue dots, s−1) responding in phase with the LiFU acoustic radiation force and (B) a second unit responding with a ∼90° phase advance relative to the stimulus. (C) Low-gain sustained-type utricular afferent responding in phase with force and (D) saccular afferent responding in phase with the stimulus.
