FRONTAL-LOBE LESIONS AND DEFICITS IN INHIBITING REFLEXIVE EYE-MOVEMENTS by Weintraub, S, Daffner, K, Scinto, L, Gitelman, D, Nobre, A, Mesulam, M

Filtering of distractors during visual search studied by positron emission tomography. by Nobre, A, Sebestyen, G, Gitelman, DR, Frith, C, Mesulam, M

“…Task conditions involved either visual search or predetermined simple eye movements for the detection of target digits. Furthermore, visual displays either contained letter foils that required filtering or contained only target digits. …”

The attentive homunculus: now you see it, now you don't. by Nobre, A

“…The findings suggested a sensible view of the attentional 'homunculus' as a distributed neural system related to the control of eye movements. Eye movements form perhaps the most basic orienting response, and can be shifted rapidly and efficiently based on multiple frames of reference. …”

Cortical activation in the human brain during lateral saccades using EPISTAR functional magnetic resonance imaging. by Darby, D, Nobre, A, Thangaraj, V, Edelman, R, Mesulam, M, Warach, S

“…The location of the human cortical substrate underlying simple horizontal saccadic eye movements was investigated using echoplanar functional magnetic resonance imaging (fMRI) in young healthy volunteers. …”

Covert visual spatial orienting and saccades: overlapping neural systems. by Nobre, A, Gitelman, DR, Dias, E, Mesulam, M

“…We used functional magnetic resonance imaging (fMRI) to investigate the functional anatomical relationship between covert orienting of visual spatial attention and execution of saccadic eye movements. Brain areas engaged by shifting spatial attention covertly and by moving the eyes repetitively toward visual targets were compared and contrasted directly within the same subjects. …”

Functional localization of the system for visuospatial attention using positron emission tomography. by Nobre, A, Sebestyen, G, Gitelman, DR, Mesulam, M, Frackowiak, R, Frith, C

“…Six right-handed male subjects were selected from a pilot behavioural study in which behavioural responses and eye movements were recorded. The attention tasks involved covert shifts of attention, where peripheral cues indicated the location of subsequent target stimuli to be discriminated. …”

Qualitative mapping of cerebral blood flow and functional localization with echo-planar MR imaging and signal targeting with alternating radio frequency. by Edelman, R, Siewert, B, Darby, D, Thangaraj, V, Nobre, A, Mesulam, M, Warach, S

“…CBF changes in the motor strip, primary visual cortex, and the motor area for eye movements were well localized to the cortical gray matter ribbon. …”

A large-scale distributed network for covert spatial attention: further anatomical delineation based on stringent behavioural and cognitive controls. by Gitelman, DR, Nobre, A, Parrish, T, LaBar, K, Kim, Y, Meyer, JR, Mesulam, M

“…This study applied more stringent behavioural and cognitive controls than previously used for similar experiments: (i) subjects were included only if they showed evidence of attentional shifts while performing the task in the magnet; (ii) the experimental task and baseline condition were designed to eliminate the contributions of motor output, visual fixation, inhibition of eye movements, working memory and the conditional (no-go) component of responding. …”
