Figure 3.

Resulting waveforms of moving phase window method. Bottom phase axis denoted in C by both radians and descriptive terms signifying respiratory phase. Dotted lines (A,B) show means and 99.73% confidence intervals for surrogate resampling distributions (n = 10,000). (A). TBR at π/4 radian window size, with 0.25 radian iterative advance (solid black line) and π/30 (unfilled squares; zero overlap) used in statistical analysis. (B). PD waveform (from normalized pupil time series) using the same methodology as A (above). Unfilled circles indicate π/30 moving phase window (zero overlap) data points. (C). ERSP at π/30 (non-overlapped) resolution, baseline subtracted. Note prominent alpha-respiratory synchronization during early inhalation.
