Mydriasis pupil) or overactivity of the sympathetic nervous system (SNS). Pupil diameter also increases in reaction to cognitive tasks requiring memory and attention, and this phenomenon is used as an indicator of mental activation (‘arousal’) in psychophysiological experiments . Natural release of the hormone oxytocin can cause mild to moderate mydriasis. Parasympathetic fibers travel with cranial nerve III, the oculomotor nerve, to innervate the circular layer of muscle of the eye (sphincter pupillae). Damage to this nerve typically manifests itself as mydriasis, because the sympathetic supply to the pupil, which causes mydriasis, remains unaffected, and therefore unopposed.

Net-widening effect Net-widening effect A net-widening effect is when administrative or practical changes result in a greater number of individuals being controlled by the criminal justice system. Many policies and practices makes it easier for the government to expand the scope of its ability to catch and punish those who have committed crimes or are deemed to be at high risk of committing crimes.
