Shape perception reduces activity in human primary visual cortex
Visual perception involves the grouping of individual elements into coherent patterns that reduce the descriptive complexity of a visual scene. The physiological basis of this perceptualExpand

Attention increases neural selectivity in the human lateral occipital complex
It is well established that attention increases the efficiency of information processing, but the neural mechanisms underlying this improvement are not fully understood. Evidence indicates thatExpand

Orientation-tuned FMRI adaptation in human visual cortex.
Adaptation is a general property of almost all neural systems and has been a longstanding tool of psychophysics because of its power to isolate and temporarily reduce the contribution of specificExpand

Although visual spatial attention has been shown to increase activity as measured with both fMRI and electrophysiological techniques, significant differences in the results have been shown. fMRIExpand

Hemispheric Asymmetry in Global/Local Processing: Effects of Stimulus Position and Spatial Frequency
We examined the neural mechanisms of functional asymmetry between hemispheres in the processing of global and local information of hierarchical stimuli by measuring hemodynamic responses withExpand

Processing Shape, Motion and Three-dimensional Shape-from-motion in the Human Cortex
Shape and motion are complementary visual features and each appears to be processed in unique cortical areas. However, object motion is a powerful cue for the perception of three-dimensional (3-D)Expand

Attention-Dependent Representation of a Size Illusion in Human V1
One of the most fundamental properties of human primary visual cortex (V1) is its retinotopic organization, which makes it an ideal candidate for encoding spatial properties, such as size, ofExpand

Perceptual grouping and inverse fMRI activity patterns in human visual cortex.
We used functional magnetic resonance imaging (fMRI) to measure activity in human visual cortex, including a higher object processing area, the lateral occipital complex (LOC), and primary visualExpand

Perceptual grouping and the interactions between visual cortical areas
Visual perception involves the grouping of individual elements into coherent patterns, such as object representations, that reduce the descriptive complexity of a visual scene. The computational andExpand

Duration-dependent FMRI adaptation and distributed viewer-centered face representation in human visual cortex.
Two functional magnetic resonance imaging (fMRI) face viewpoint adaptation experiments were conducted to investigate whether fMRI adaptation in high-level visual cortex depends on the duration ofExpand
