Attentional Mechanisms in Ventral Pathway
2009Attentional modulation along the ventral pathway of the cortical visual system of primates consists in enhanced representation of the retinal input at a specific location in space, or of objects located anywhere in the visual field which possess a critical feature.

Neural mechanisms of social attention
Trends in Cognitive Sciences, 2009Social attention is conveyed primarily by gaze, but also by head and body orientation. These cues not only signal a seen agent's direction of attention but are also used to infer their current goals and intentions. Here, we review recent research showing that different gaze, head and body orientations are represented by distinct neural mechanisms, and ...

Soviet Psychology, 1969
There have been several attempts in the field of psychology to explain attention mechanisms on the basis of negative inductive relationships. Such an interpretation has certain justifications vis-a-vis the lower forms of attention, usually characterized as involuntary.

A brain mechanism for attention
Medical Hypotheses, 1990Attention is directed or focussed consciousness. Consciousness is a subjective sensation produced by the simultaneous activation of discrete neurophysiological systems. These are the alerting, awareness, affect, arousal, and attention systems. The process begins with the subcortical scanning of sensory stimuli for affect and significance via pleasure ...

Mechanisms of attentional priority.
Journal of Experimental Psychology: Human Perception and Performance, 1990When a single abrupt onset occurs in a multielement visual display, it captures attention, possibly by generating an attentional interrupt that designates onsets as being of high priority. In 3 experiments, the mechanisms subserving attentional priority setting were investigated.

This chapter reviews some of the studies demonstrating that attention is associated with an increase in activity in the brain region concerned with the processing of whatever it is that is being attended to. The basic assumption is that there is competition between stimuli for processing by the nervous system.

Probing the Mechanisms of Attention
2009ABSTR/TCT This chapter emphasizes the manlr methods currently being employed to study brain networks related to attcntion. We seek to sct current studies into a historical background of efforts to understand how the brain selects among stimuli and resolves competing responses.

AbstractThis chapter examines the classical psychophysical view of selective visual attention, and the physiological findings that suggest an alternative neurodynamical view based on the biased competition hypothesis. It discusses the computational models of visual attention, the biased competition hypothesis in single-cell studies, and the ...
