A Rhythmic Theory of Attention

Ian C. Fiebelkorn, Sabine Kastner
2019 Trends in Cognitive Sciences  
Both perceptual sensitivity during covert spatial attention and the probability of overt exploratory movements are tethered to theta-band activity (3-8Hz) in the attention network.  ...  The fronto-parietal part of this network is positioned at the nexus of sensory and motor functions, directing two tightly coupled processes related to environmental exploration: preferential routing of  ...  Classic studies of spatial attention largely ignored its temporal dynamics, assuming that associated neural and behavioral effects were continuous over time and persisted for the duration of attentional  ...

Functional but not obligatory link between microsaccades and neural modulation by covert spatial attention [article]

Baiwei Liu, Anna C. Nobre, Freek van Ede
2021 bioRxiv   pre-print
Critically, however, trials without attention-driven microsaccades nevertheless showed clear spatial modulation of alpha activity – comparable to the neural modulation observed in trials with attention-driven  ...  Recently, this link has been suggested to be obligatory, such that modulation of neural activity by covert spatial attention occurs only when paired with microsaccades toward the attended location.  ...  Here we revisited the nature of this link between microsaccades and modulation of neural activity by covert spatial attention in humans.  ...

Covert Shift of Attention Modulates the Ongoing Neural Activity in a Reaching Area of the Macaque Dorsomedial Visual Stream

Claudio Galletti, Rossella Breveglieri, Markus Lappe, Annalisa Bosco, Marco Ciavarro, Patrizia Fattori, Bart Krekelberg
2010 PLoS ONE  
We found that neurons in V6A are influenced by spatial attention. The attentional modulation occurs without gaze shifts and cannot be explained by visual stimulations.  ...  Attention is used to enhance neural processing of selected parts of a visual scene. It increases neural responses to stimuli near target locations and is usually coupled to eye movements.  ...  Acknowledgments The authors are grateful to Nicoletta Marzocchi and Konstantinos Chatzidimitrakis for help in some recording sessions and to Giacomo Placenti for assistance in the data analysis.  ...

Neuroanatomic Overlap of Working Memory and Spatial Attention Networks: A Functional MRI Comparison within Subjects

1999 NeuroImage  
The spatial attention task required the subject to shift visual attention covertly in response to a centrally presented directional cue.  ...  The presence of this overlap also suggests that spatial attention and working memory share common cognitive features related to the dynamic shifting of attentional resources. 1999 Academic Press Major  ...  ACKNOWLEDGMENTS The authors thank Yun-Hee Kim for assistance with developing the attention task, Cathy Callahan for assistance with MR scanning, and Shelly Huddle for assistance with data analysis.  ...

Visual and oculomotor selection: links, causes and implications for spatial attention

Edward Awh, Katherine M. Armstrong, Tirin Moore
2006 Trends in Cognitive Sciences  
Past studies have provided compelling evidence of functional overlap of the neural mechanisms that control spatial attention and saccadic eye movements.  ...  Recent neurophysiological work demonstrates that the neural circuits involved in the preparation of saccades also play a causal role in directing covert spatial attention.  ...  The approach of directly manipulating signals in these areas is particularly valuable in that it addresses the causal relationship between neural activity in oculomotor circuits and shifts of spatial attention  ...

Cortical mechanisms of space-based and object-based attentional control

Steven Yantis, John T Serences
2003 Current Opinion in Neurobiology  
Subregions of parietal and frontal cortex are transiently active when attention is voluntarily shifted between spatial locations or object representations.  ...  This transient activity may reflect an abrupt shift in the attentional set of the observer, complementing sustained signals that are thought to maintain a given attentive state.  ...  . of spatial attention shifts.  ...

J. J. Green, S. M. Doesburg, L. M. Ward, J. J. McDonald
