Relationships between pupil diameter and neuronal activity in the locus coeruleus, colliculi, and cingulate cortex (2015, background): “…activity and pupil diameter, and common factors that drive LC and pupil changes (Phillips et al., 2000; Hou et al., 2005; Beatty, 1982a, 1982b; Richer and Beatty, 1987; Einhäuser et al., 2008; Gilzenrat et al., 2010; Morad et al., 2000; Aston-Jones and Cohen, 2005; Murphy et al., 2011, 2014).”

Beyond eye gaze: What else can eyetracking reveal about cognition and cognitive development? (2016, background): “3; Costa and Rudebeck, 2016; Joshi et al., 2016; Rajkowski et al., 1993; Varazzani et al., 2015), and fMRI studies have shown corresponding links between LC BOLD signals and pupil diameter in humans (Alnaes et al., 2014; Murphy et al., 2014).”
Waking State: Rapid Variations Modulate Neural and Behavioral Responses (2015, positive): “Human and animal studies have shown that changes in pupil diameter (after controlling for changes associated with luminance and depth accommodation) are correlated with arousal, attention, emotion, cognitive perception, and ‘‘brain gain,’’ as well as heart rate and galvanic skin reflex, indicating a”
