Evoked VCR head movements show quasilinear relationship as the
stimulation rate and the current amplitude increase. A-C) Similar to Fig. 3 but shows the evoked VCR head velocity
as a function of stimulation rate using 250, 188, and 125 uA, respectively. D-E)
Evoked head velocity as a function of current amplitude using 600 and 400 pps,
respectively. Inset shows the vector representation of the response of the
electrode pair used. Error bars show one standard deviation. Blue, green, and
red signify the directions of the -RALP, -LARP, and Z/LHRH, respectively.
