Practising orientation identification improves orientation coding in V1 neurons
The adult brain shows remarkable plasticity, as demonstrated by the improvement in fine sensorial discriminations after intensive practice. The behavioural aspects of such perceptual learning areExpand

Stereopsis Activates V3A and Caudal Intraparietal Areas in Macaques and Humans
Stereopsis, the perception of depth from small differences between the images in the two eyes, provides a rich model for investigating the cortical construction of surfaces and space. AlthoughExpand

Motion-responsive regions of the human brain
Abstract Functional magnetic resonance imaging was used to map motion responsive regions of the human brain by contrasting passive viewing of moving and stationary randomly textured patterns. RegionsExpand

The Retinotopic Organization of the Human Middle Temporal Area MT/V5 and Its Cortical Neighbors
Although there is general agreement that the human middle temporal (MT)/V5+ complex corresponds to monkey area MT/V5 proper plus a number of neighboring motion-sensitive areas, the identification ofExpand

Human velocity and direction discrimination measured with random dot patterns
In the present experiments three different motion discrimination tasks were studied using a random dot pattern as stimulus: velocity discrimination, direction discrimination and discrimination ofExpand

The kinetic occipital (KO) region in man: an fMRI study.
We used functional magnetic resonance imaging to explore, in individual subjects, the properties of the kinetic occipital (KO) region, which previous position emission tomography studies have shownExpand

Human perceptual learning in identifying the oblique orientation: retinotopy, orientation specificity and monocularity.
1. Human perceptual learning in discrimination of the oblique orientation was studied using psychophysical methods. Subjects were trained daily to improve their ability to identify the orientation ofExpand

Responses of macaque STS neurons to optic flow components: a comparison of areas MT and MST.
1. We recorded and tested quantitatively 65 middle temporal (MT) and 82 middle superior temporal (MST) cells in paralyzed and anesthetized monkeys. 2. Responses to the three elementary optic flowExpand

Shape and Spatial Distribution of Receptive Fields and Antagonistic Motion Surrounds in the Middle Temporal Area (V5) of the Macaque
The spatial organization of receptive fields in the middle temporal (MT) area of anaesthetized and paralysed macaque monkeys was studied. In all, 288 neurons were successfully recorded. The size andExpand

Comparative mapping of higher visual areas in monkeys and humans
The advent of functional magnetic resonance imaging (fMRI) in non-human primates has facilitated comparison of the neurobiology of cognitive functions in humans and macaque monkeys, the mostExpand
