Fig. 9. Comparison of the average RMS field potentials associated with C-starts
that do (solid lines) or do not (broken lines) exhibit counterturns. RMS field
potentials were aligned at the onset of the individual responses. Error bars
are ± 1 s.d. Horizontal arrows indicate the time sequence at which the
different stages of the escape behavior take place following the onset of the
M-spike (vertical arrow).
