Fig. 5. Distribution of interspike intervals (ISIs) between all spikes within a
burst compared between flat (A) and rough (B) terrain running. Neither the
individual animal nor the order of the spiking event in the step (time between
first and second spike vs time between second and third spike)
significantly affected the distribution. Running speed did correlate with ISI
and was corrected for in the normalized ISI values (C,D). No significant
differences between terrain type were present in normalized ISI
distributions.
