This study shows that pupil diameter is not reliably linked to locus coeruleus activity modes, suggesting caution in using pupil size as a proxy for phasic and tonic LC-NE activity.

The paper uses intracranial recordings to show that nociception and salience have distinct neural representations in the human brain, with different anatomical, temporal, and functional characteristics.

The paper examines neural responses to salient auditory stimuli using intracranial electrodes, finding two distinct temporal stages of activation: phasic sensorimotor and sustained salience network responses.

The paper shows that locus coeruleus (LC) activation in awake monkeys affects coordinated activity patterns in the anterior cingulate cortex (ACC), with effects varying based on the type of LC activation and associated pupil changes.

The paper identifies multiple functional clusters of neurons in layer 6 of macaque V1 based on their response to visual stimuli, revealing distinct sub-populations with different visual properties.
