Hemispheric asymmetry for trajectory perception.

Broadly, the right hemisphere is known to be specialized for spatial processing whereas the left hemisphere is known to be specialized for temporal processing. However, it remains unclear how both hemispheres interact when processing spatio-temporal ...

Cortical activity reduction with stimulus repetition: a whole-head MEG analysis.

Event related field responses to line drawings of novel visual objects were recorded in a simple target detection task using whole-head magnetoencephalography. Brain-current-source-density reconstruction indicated that, relative to initial presentations, ...

The generators of slow potentials obtained during verbal, pictorial and spatial tasks.

The purpose of this study was to test whether slow cortical electrical activity is specific to performance on verbal, pictorial and spatial tasks. Twenty-nine healthy subjects were required to compare pairs of visual stimuli separated by a delay of 2.5 s ...

Phonological processing during language production: fMRI evidence for a shared production-comprehension network.

Studies of phonological processes during language comprehension consistently report activation of the superior portion of Brocas area. In the domain of language production, however, there is no unequivocal evidence for the contribution of Brocas area to ...

Subjective visual experience during phacoemulsification cataract surgery under sub-Tenons block.

In a prospective survey, 121 patients received sub-Tenons block and were interviewed on the same day after their phacoemulsification cataract surgery regarding their visual experience in the operated eye during surgery. Majority of patients (81%) ...

Orientational minimal redundancy wavelets: from edge detection to perception.

Natural images are complex but very structured objects and, in spite of its complexity, the sensory areas in the neocortex in mammals are able to devise learned strategies to encode them efficiently. How is this goal achieved? In this paper, we will ...

Grasp effects of the Ebbinghaus illusion: obstacle avoidance is not the explanation.

The perception-versus-action hypothesis states that visual information is processed in two different streams, one for visual awareness (or perception) and one for motor performance. Previous reports that the Ebbinghaus illusion deceives perception but ...

Mechanisms underlying interlimb transfer of visuomotor rotations.

We previously reported that opposite arm training improved the initial direction of dominant arm movements, whereas it only improved the final position accuracy of non-dominant arm movements. We now ask whether each controller accesses common, or ...

Clinical value of the Beery visual-motor integration supplemental tests of visual perception and motor coordination.

PURPOSE: Children may perform poorly on a test of visual-motor integration due to deficits in one or more of the following: visual analysis/visual spatial ability, motor coordination, visual conceptualization, or visual-motor integration. The VMI ...

Neural correlates of lexical access during visual word recognition.

People can discriminate real words from nonwords even when the latter are orthographically and phonologically word-like, presumably because words activate specific lexical and/or semantic information. We investigated the neural correlates of this ...
