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 …

[HTML][HTML] A practical introduction to using the drift diffusion model of decision-making in cognitive psychology, neuroscience, and health sciences
Recent years have seen a rapid increase in the number of studies using evidence-
accumulation models (such as the drift diffusion model, DDM) in the fields of psychology and …

Pupil-linked phasic arousal predicts a reduction of choice bias across species and decision domains
Decisions are often made by accumulating ambiguous evidence over time. The brain's
arousal systems are activated during such decisions. In previous work in humans, we found …

Pupil diameter is not an accurate real-time readout of locus coeruleus activity
M Megemont, J McBurney-Lin, H Yang - Elife, 2022 - elifesciences.org
Pupil diameter is often treated as a noninvasive readout of activity in the locus coeruleus
(LC). However, how accurately it can be used to index LC activity is not known. To address …

[HTML][HTML] Rapid effects of vagus nerve stimulation on sensory processing through activation of neuromodulatory systems
After sensory information is encoded into neural signals at the periphery, it is processed
through multiple brain regions before perception occurs (ie, sensory processing). Recent …

Locus coeruleus spiking differently correlates with S1 cortex activity and pupil diameter in a tactile detection task
We examined the relationships between activity in the locus coeruleus (LC), activity in the
primary somatosensory cortex (S1), and pupil diameter in mice performing a tactile detection …

More than a feeling: scalp EEG and eye signals in conscious tactile perception
Understanding the neural basis of consciousness is a fundamental goal of neuroscience,
and sensory perception is often used as a proxy for consciousness in empirical studies …

[HTML][HTML] Perceptual behavior depends differently on pupil-linked arousal and heartbeat dynamics-linked arousal in rats performing tactile discrimination tasks
Several physiology signals, including heart rate and pupil size, have been widely used as
peripheral indices of arousal to evaluate the effects of arousal on brain functions. However …
