Selective visual attention describes the tendency of visual processing to be confined largely
to stimuli that are relevant to behavior. It is among the most fundamental of cognitive …

A basic feature of intelligent systems such as the cerebral cortex is the ability to freely
associate aspects of perceived experience with an internal representation of the world and …

Emotional arousal enhances perception and memory of high-priority information but impairs
processing of other information. Here, we propose that, under arousal, local glutamate levels …

Sensory systems must rely on powerful mechanisms for organizing complex information. We
propose a framework in which inhibitory alpha oscillations limit and prioritize neuronal …

Inherent in visual scene analysis is a bottleneck associated with the need to sequentially
sample locations with foveating eye movements. The concept of a 'saliency …

Spatial priority maps are real-time representations of the behavioral salience of locations in
the visual field, resulting from the combined influence of stimulus driven activity and top …

Exogenous attention, the process that makes external salient stimuli pop-out of a visual
scene, is essential for survival. How attention-capturing events modulate human brain …

Attention improves perception by affecting different aspects of the neuronal code. It
enhances firing rates, it reduces firing rate variability and noise correlations of neurons, and …

Whether an object captures our attention depends on its bottom-up salience, that is, how
different it is compared with its neighbors, and top-down control, that is, our current inner …

Learning from reward feedback is essential for survival but can become extremely
challenging with myriad choice options. Here, we propose that learning reward values of …
