Figure 4.
Average for all eight startle sound events together (no other stress provocation), including all six muscles (Alfvén et al 2017 6, for: (A) Mean amplitude (µV) during 200 ms from OR‐activity‐start and during burst, (B) Burst duration and latency (ms) from sound to muscle‐activity‐start (≥10 µV), (C) Average amount of bursts:–mean of 1.0 = all muscles burst (peak ≥ 10 µV) and 2.0 = no muscle had burst (peak ≥ 10 µV) in any of the eight stimuli. PAIN versus CON showed significant differences (star). (OR = orbicularis oculi).
