Neural Mechanisms of Attention

1993
Much of our current knowledge of the neural substrates of attention has come from neurophysiological investigations that initially focused on characterizing how sensory and motor system of the brain function. Studies of the neural bases of conditioning have provided a second important source of information.

Attentive mechanisms in visual search

Spatial Vision, 2004
Selective attention can be employed to a restricted region in space or to specific objects. Many properties of this attentional window or spotlight are not well understood. In the present study, we examined the question whether the putative shape of the attentional spotlight can be determined by endogenous cueing within a visual search paradigm ...

Mechanisms of attention: A developmental study

Journal of Experimental Child Psychology, 1989
A model of selective attention is proposed which contains a number of properties. First, stimuli which are irrelevant to the subjects' task can be analyzed to semantic levels automatically, and such stimuli can produce intrusion/interference effects.

Models and Mechanisms of Attention

2013
Attention has been studied from a variety of different theoretical and scientific perspectives ranging from the examination of cellular mechanisms such as the graded potentials of single neurons to the complex systems encompassing multiple brain regions underlying consciousness.

Mechanisms of top-down attention

Trends in Neurosciences, 2011
Attention exhibits characteristic neural signatures in brain regions that process sensory signals. An important area of future research is to understand the nature of top-down signals that facilitate attentional guidance towards behaviorally relevant locations and features.

Probing the Mechanisms of Attention

2009
ABSTR/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.

Neurophysiological Mechanisms of Attention

Soviet Psychology, 1980
According to contemporary notions, the functional states of the brain are stages of a single continuum, the lower limit of which is a state of coma and sleep, and the upper limit, a state of hyperexcitation and alertness [2, 6, 24, 28, 32, and others].

Neuronal Mechanisms of Attentional Control

2014
Damage to the human inferior parietal lobe produces an attentional disturbance known as contralateral neglect, and neurophysiological studies in monkeys have begun to unravel the cellular basis of this function. Converging evidence suggests that LIP encodes a sparse topographic map of the visual world that highlights attention-worthy objects or ...
