First off, thank you for making me look this up, as I now learned something new :)
If I understand this correctly, the immediate fight-or-flight response is triggered by noradrenaline, which is very similar to adrenaline but released by nerve cells directly to places all over the body, increasing blood flow and pressure, alertness, etc (but not affecting muscles). Adrenaline gets released into the blood via stimulation by the sympathetic system, but its effects last longer.
So it seems noradrenaline, by the fact that it's released directly from nerve cells, basically dictates how fast a person processes immediate external stimuli, and could possibly explain "super perception"
