A novel method for modeling tonic and phasic pupil dynamics in humans

2025-05-12

Abstract excerpt

<p>The human pupil is a widely used physiological metric in psychology and neuroscience. Changes in pupil diameter (PD) are thought to reflect changes in locus coeruleus-norepinephrine (LC/NE) activity, which is associated with cognitive and behavioral optimization. Here, we present novel algorithms to decompose the pupil signal into its tonic and phasic components. We evaluate the utility and validity of the algo...
