The course of pupillary constriction and dilation provides an easy-to-access, inexpensive,
and noninvasive readout of brain activity. We propose a new taxonomy of factors affecting …

Our subjective visual experiences involve complex interaction between our eyes, our brain,
and the surrounding world. It gives us the sense of sight, color, stereopsis, distance, pattern …

Cognitive pupillometry is the measurement of pupil size to investigate cognitive processes
such as attention, mental effort, working memory, and many others. Currently, there is no …

If the eyes are windows into the soul, then the pupils represent at least the gateway to the
brain and can provide a unique insight into the human mind from several aspects. The …

Pupillometry is widely used to measure arousal states. The primary functional role of the
pupil, however, is to respond to the luminance of visual inputs. We previously demonstrated …

The human pupil behavior has gained increased attention due to the discovery of the
intrinsically photosensitive retinal ganglion cells and the afferent pupil control path's role as …

Working memory is integral to a range of critical cognitive functions such as reasoning and
decision‐making. Although alterations in working memory have been observed in …

Saccadic eye movements are directed to the objects of interests and enable high-resolution
visual images in the exploration of the visual world. There is a trial-to-trial variation in …

Pupillometry has become a standard measure for assessing arousal state. However,
environmental factors such as luminance, a primary dictator of pupillary responses, often …

Pupil size reflects a proxy for neural activity associated with global luminance, arousal and
cognitive processing. Microsaccades are also modulated by arousal and cognitive …
