Cortex dynamically regulates the flow of sensory information by suppressing responses of non-relevant stimuli through mechanisms of adaptation, while boosting sensory responses that are behaviorally important.
Populations of neurons in the macaque visual cortex are subject to shared fluctuations in gain; these signals exhibit anatomical and functional structure, and their variability is diminished under attention.
A direct relationship between pupil diameter and electrophysiological correlates of attention, sensory stimulus processing and target detection was observed demonstrating that arousal has a substantial influence on perceptual decision-making.
People who have attempted suicide exhibit blunted sensory processing during breathing and pain perturbations, as well as lower heartbeat perception accuracy and reduced mid/posterior insula activity during interoceptive attention.
An analysis of review, promotion and tenure documents from 129 US and Canadian universities suggests institutions could better fulfill their public missions by changing how they incentivize the public dimensions of faculty work.
