The beginning of a train was set as the beginning of the first impulse after a period where the interpulse interval was > [I.
4 ms (n = 27), and was similar to the mean interpulse interval of a chirp sampled at random from a cage with O.
The means and standard errors of the interpulse intervals of the second chirp (i.
To consider the range of chirp durations and interpulse intervals that can be expected in different O.

The beginning of a train was set as the beginning of the first valid impulse after a period where the interpulse interval was > [I.
3A, but rather a mixture of low- and high-amplitude impulses that occurred in well-defined trains with short interpulse intervals, separated by 0.
albisella produce loud and organized pulsed calls that are very consistent in such temporal qualities as pulse rate, individual pulse duration, interpulse interval
duration, call duration, and number of pulses in a call (4, 5).
We assessed HR; beats per second--a HR calculated in the average-value interpulse intervals
in the analyzed sample; SYM--an activity index of the sympathetic part of the autonomic nervous system; PAR (relative value unit [rvu])--an activity index of the parasympathetic autonomic nervous system; INB (rvu)--tension index characterizing the centralization degree of regulatory influences on the HR; HF (high frequency wave power in the range from 0.
