The neural bases of visual attention
Archive ouverte
International audience. Selective attention, a fundamental cognitive mechanism, has been a focus of research since the early 20th century due to itsessential role in numerous other cognitive functions like perception, working-memory, decision-making, and socialcognition. It enables the filtering and prioritization of behaviorally significant information, thereby enhancing perceptionand response accuracy to sensory stimuli. This cognitive function is particularly well studied for the visual modality, and isthought to have evolved alongside the expansion of the visual systems in primates, underscoring an evolutionary advantagefor efficient information processing. The article aims to delve into the dynamics of how attention is controlled, leveragingresearch on non-human primates to explore the neural underpinnings of selective attention, including the principal brainregions involved, neural markers at the individual neuron level, and the dynamic interactions across neural networks.
