Cycle-by-cycle transient changes in the studied intervals. Panel (A), intervals \(Period\), \(B{D}_{LP}\), \(B{D}_{PD}\), \(LPPD\,delay\), \(LPPD\,interval\) and \(PDLP\,delay\) for each cycle. Note that despite the variability in period, \(LPPD\,delay\) and \(LPPD\,interval\) closely follow it. Panel (B) shows the intervals as in Panel A but with standardized duration. In this representation, the variability of all intervals are in the same range. Note that the standardized \(LPPD\,delay\), \(LPPD\,interval\) and \(Period\), which give rise to the invariants, evolve on top of each other while the evolution of the others intertwine. Analogous representation of the cycle-by-cycle transient changes under the influence of ethanol are shown in Panels (C,D). \(LPPD\,delay\) and \(LPPD\,interval\) closely track \(Period\) despite the induced variability. Both insets show a blow up to highlight the common evolution of the three intervals involved in the invariants (solid lines).
