Figure 2. Changes in FSBF, hemodynamic parameters, and EMGs time-related to finger sweat expulsion. Data were obtained from an average of 27 sweeps of waveforms from the same subject, as in Fig. 1. A temporal reference point (solid vertical line) was obtained from the onset of sweat expulsion (dotted vertical line [ ]), but the time delay in sensing humidity (3.2 ± 0.4 sec) was corrected by a shifting of the dotted vertical line to the solid vertical line (horizontal double-headed arrow). Twenty-second sweeps of waveform data around the onset of sweat expulsions were abstracted and averaged after alignment at the temporal reference point. The gray area indicates the 10-second period with its center at the temporal reference point and defined as a proximal time window to the onset of sweat expulsion (PWSE), and vertical double-headed arrows indicate maximum trace deflections within PWSE. F-Sweat, finger sweat; FSBF, finger skin blood flow; EMG, electromyogram; L, left; R, right; Temp, temporalis muscle; Mass, masseter muscle; OxyHb, oxygenated hemoglobin; DeoxyHb, deoxygenated hemoglobin; StO2, tissue blood oxygen saturation (OxyHb/TotalHb x 100).
