Studies: Alterations of norepinephrine and other neurotransmitters may affect the creative process. The minds of exceptionally creative people may be capable of regulating norepinephrine – to decrease levels during periods of creative innovation and pave the way for discovery of unanticipated associations. High levels of norepinephrine constrict the diversity of available concepts; low levels have the opposite effect. (Heilman, K. M. Creative Innovation: Possible Brain Mechanisms.9(5):369-379. Neurocase. 2003.)

Baby monkeys whose mothers are exposed to a major stress while pregnant show the signs of that stress in their temperament, displaying an inhibited temperament reflected in their altered levels of noradrenaline and dopamine.

The video-based spinning woman illusion has been making the rounds on the internet. Olivia Carter, a neuroscientist at the University of Melbourne in Australia, and her team, found that people's pupils dilate when they switch between two alternative ways of viewing an optical illusion (e.g., the woman seems to switch direction but in fact does not). The effect results from the viewer swapping how they view her. Eye pupils dilate in stressful situations as part of the "fight-or-flight" response. The reflex is mediated by the release of the hormone noradrenalin. Noradrenalin helps you to cement decisions toward which you are moving. Pupil dilation is an outward sign of this. (Source)
