Pupil response is governed by the autonomic nervous system. Pupil dilation depends on the activation of the adrenergic sympathetic nervous system, while pupil constriction depends on the cholinergic parasympathetic nervous system[1]. It has been well documented that pupil response is modulated not only by an ambient luminance level (the so-called pupil light reflex) but also by the amount of mental effort invested in a task [2][3][4][5][6][7][8][9][10][11][12]. For example, Porter et al[13] reported that the pupil dilates when subjects conduct a difficult visual search task in which high mental effort has to be invested.

Pupil size is thought to be controled by the LC-NE system see Cohen[14]and Jepma & Nieuwenhuis[15]. Neural gain, may be the same as mind clouser
