Journal ArticleDOI
Quantitative analysis of attention and detection signals during visual search
Gordon L. Shulman,Mark P. McAvoy,Melanie C. Cowan,Serguei V. Astafiev,Aaron P. Tansy,Giovanni d'Avossa,Maurizio Corbetta +6 more
TL;DR: The present results show that when subjects search for and detect a visual target stimulus among nontargets, these regions show sensory-, search- and detection-related signals that both confirm and refine functional distinctions in the intraparietal sulcus and frontal eye field.
Journal ArticleDOI
Word Retrieval Learning Modulates Right Frontal Cortex in Patients with Left Frontal Damage
Valeria Blasi,Alexis Young,Aaron P. Tansy,Steven E. Petersen,Abraham Z. Snyder,Maurizio Corbetta +5 more
TL;DR: It is shown that patients with left frontal lesions and partially recovered aphasia learn, at a normal rate, a novel word retrieval task that requires the damaged cortex, indicating that frontal cortex is a source of top-down signals during learning.
Journal ArticleDOI
Two attentional processes in the parietal lobe
TL;DR: This paper found evidence for general and specialized task representations within left parietal cortex during task preparation and execution, indicating that the information was coded in a sufficiently abstract form to affect color and motion processing.
Journal ArticleDOI
A functional MRI study of preparatory signals for spatial location and objects.
Maurizio Corbetta,Aaron P. Tansy,Christine M. Stanley,Serguei V. Astafiev,Abraham Z. Snyder,Gordon L. Shulman +5 more
TL;DR: It is concluded that under certain circumstances, spatial cues that produce strong behavioral effects may modulate parietal-occipitals regions in a spatially specific manner without producing similar modulations in retinotopic occipital regions.
Journal ArticleDOI
Reactivation of Networks Involved in Preparatory States
Gordon L. Shulman,Aaron P. Tansy,Michelle Kincade,Steven E. Petersen,Mark P. McAvoy,Maurizio Corbetta +5 more
TL;DR: It is indicated that terminating a state of readiness produces a widely distributed cortical signal and suggest that areas involved in a preparatory state may be maintained as a network which can be modulated as a whole.
