Fig. 2. Comparison of Estimated Pulse Timing and Amplitudes Using the Experimental Twenty-Four-Hour Cortisol Levels Only with Estimates from Concurrent ACTH and Cortisol Levels in 10 Women.

Fig. 2

Each panel shows the estimated pulse timing and amplitudes (blue vertical lines with dots) using concurrent measurements of ACTH and cortisol, and the estimated pulse timing and amplitudes (red vertical lines with dots) using only cortisol measurements for the corresponding participant. The shaded gray area corresponds to sleep period and the white area corresponds to wake period.
