Fig. 8. I-afferent response and PIV. (A) Averaged (n=8) vector plots based
on particle motions caused by the vortex stimulus. Particle motions were
recorded (from left to right) immediately before first threshold crossing, at
first and second threshold crossing, and 200 ms after the second threshold
crossing. (B) Raster plots of the responses and (C) peri-stimulustime
histograms (PSTHs; bin width 20 ms) based on these raster plots. See
Fig. 7 for further details.
