Pupillometry as an integrated readout of distinct attentional networks
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 …

Balancing exploration and exploitation with information and randomization
Explore-exploit decisions require us to trade off the benefits of exploring unknown options to
learn more about them, with exploiting known options, for immediate reward. Such decisions …

Phasic activation of dorsal raphe serotonergic neurons increases pupil size
Transient variations in pupil size (PS) under constant luminance are coupled to rapid
changes in arousal state, 1–3 which have been interpreted as vigilance, 4 salience, 5 or a …
