7 Synergetic Interpretation of Patterned Vasomotion Activity …

Fig. 7.2 Typical example of the temporal evolution of the ca 0.15 Hz activity in a naively relaxing
subject. Note the gradual appearance of the activity in the range between 0.1 Hz and 0.2 Hz (stippled
peaks), associated with gradually emerging activity in the range between 0.01 Hz and 0.1 Hz (low
frequency band activity not associated with sympathetic nerve activity). Note also the absence of
activity in the range of respiratory activity (0.25 Hz–0.3 Hz)
Fig. 7.3 Various examples of the emergence of ca 0.15 Hz activity in the reflection photoplethysmographic records from the locally heated (29 °C–31 °C) in subjects where the local microvascular
tone, but perhaps not the tone in the larger arteries supplying the forehead skin was eliminated
