Delirium, a syndrome characterized by an acute change in attention, awareness and
cognition, is caused by a medical condition that cannot be better explained by a pre-existing …

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 …

While insomnia is the second most common mental disorder, progress in our understanding
of underlying neurobiological mechanisms has been limited. The present review addresses …

Decades of neurobiological research have disclosed the diverse manners in which the
response properties of neurons are dynamically modulated to support adaptive cognitive …

The locus coeruleus (LC), or 'blue spot', is a small nucleus located deep in the brainstem
that provides the far-reaching noradrenergic neurotransmitter system of the brain. This …

Cognitively driven pupil modulations reflect certain underlying brain functions. What do
these reflections tell us? Here, we review findings that have identified key roles for three …

The rapid and coordinated propagation of neural activity across the brain provides the
foundation for complex behavior and cognition. Technical advances across neuroscience …

Pupillometry research has experienced an enormous revival in the last two decades. Here
we briefly review the surge of recent studies on task-evoked pupil dilation in the context of …

What are the principles underlying effective neurorehabilitation? The aim of
neurorehabilitation is to exploit interventions based on human and animal studies about …

Pupils respond to three distinct kinds of stimuli: they constrict in response to brightness (the
pupil light response), constrict in response to near fixation (the pupil near response), and …
