A saliency-based search mechanism for overt and covert shifts of visual attention
Most models of visual search, whether involving overt eye movements or covert shifts of attention, are based on the concept of a saliency map, that is, an explicit two-dimensional map that encodes the saliency or conspicuity of objects in the visual environment. Competition among neurons in this map gives rise to a single winning location that corresponds to the next attended target. Inhibiting...
متن کاملOvert Selection and Processing of Visual Stimuli
To see is to act. Most obviously, we are continuously scanning different regions of the world with the movement of our eyes, head, and body. These overt movements are intrinsically linked to two other, more subtle, actions: (1) the prior process of deciding where to look; and (2) the prediction of the sensory consequences of overt movements. In this thesis I describe a series of experiments tha...

متن کاملOn the origin of event-related potentials indexing covert attentional selection during visual search.
Despite nearly a century of electrophysiological studies recording extracranially from humans and intracranially from monkeys, the neural generators of nearly all human event-related potentials (ERPs) have not been definitively localized. We recorded an attention-related ERP component, known as the N2pc, simultaneously with intracranial spikes and local field potentials (LFPs) in macaques to te...
متن کاملOvert Responses during Covert Orienting
A distributed network of cortical and subcortical brain areas controls our oculomotor behavior. This network includes the superior colliculus (SC), which coordinates an ancient visual grasp reflex via outputs that ramify widely within the brainstem and spinal cord, accessing saccadic and other premotor and autonomic circuits. In this Review, we discuss recent results correlating subliminal SC a...
