Different states in visual working memory: When it guides attention and when it does not

CNL Olivers, J Peters, R Houtkamp… - Trends in cognitive …, 2011 - cell.com
Recent studies have revealed a strong relationship between visual working memory and
selective attention, such that attention is biased by what is currently on our mind. However …

Control of visual cortical signals by prefrontal dopamine

B Noudoost, T Moore - Nature, 2011 - nature.com
The prefrontal cortex is thought to modulate sensory signals in posterior cortices during top-
down attention,, but little is known about the underlying neural circuitry. Experimental and …

Neural mechanisms of saccade target selection: gated accumulator model of the visual–motor cascade

JD Schall, BA Purcell, RP Heitz… - European Journal of …, 2011 - Wiley Online Library
We review a new computational model developed to understand how evidence about
stimulus salience in visual search is translated into a saccade command. The model uses …

Deficits in reach target selection during inactivation of the midbrain superior colliculus

JH Song, RD Rafal, RM McPeek - Proceedings of the …, 2011 - National Acad Sciences
Purposive action requires the selection of a single movement goal from multiple possibilities.
Neural structures involved in movement planning and execution often exhibit activity related …

Stimulus-driven orienting of visuo-spatial attention in complex dynamic environments

D Nardo, V Santangelo, E Macaluso - Neuron, 2011 - cell.com
In everyday life attention operates within complex and dynamic environments, while
laboratory paradigms typically employ simple and stereotyped stimuli. This fMRI study …

Gain modulation by an urgency signal controls the speed–accuracy trade-off in a network model of a cortical decision circuit

D Standage, H You, DH Wang… - Frontiers in computational …, 2011 - frontiersin.org
The speed–accuracy trade-off (SAT) is ubiquitous in decision tasks. While the neural
mechanisms underlying decisions are generally well characterized, the application of …

Pre-stimulus activity predicts the winner of top-down vs. bottom-up attentional selection

A Mazaheri, NE DiQuattro, J Bengson, JJ Geng - PloS one, 2011 - journals.plos.org
Our ability to process visual information is fundamentally limited. This leads to competition
between sensory information that is relevant for top-down goals and sensory information that …

Visual selection and the human frontal eye fields: effects of frontal transcranial magnetic stimulation on partial report analyzed by Bundesen's theory of visual attention

J Hung, J Driver, V Walsh - Journal of Neuroscience, 2011 - Soc Neuroscience
While the frontal eye fields (FEF) are traditionally associated with eye movements, recent
work indicates possible roles in controlling selective visual processing. We applied 10 Hz …

The relationship between spatial attention and saccades in the frontoparietal network of the monkey

C Wardak, E Olivier, JR Duhamel - European Journal of …, 2011 - Wiley Online Library
Spatial attention bears a remarkable resemblance to saccadic eye movements from both a
behavioural and a neurophysiological point of view. In this review, we examine the …
