Practising orientation identification improves orientation coding in V1 neurons
Improved long-term neuronal performance resulted from changes in the characteristics of orientation tuning of individual neurons, which induces a specific and efficient increase in neuronal sensitivity in V1 of monkeys for learning orientation identification.
Motion-responsive regions of the human brain
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, and flicker-induced-activation introduced a dichotomy amongst these motionresponsive regions.
Human perceptual learning in identifying the oblique orientation: retinotopy, orientation specificity and monocularity.
Human perceptual learning in discrimination of the oblique orientation was studied using psychophysical methods and suggests plastic changes at a level of the visual processing stream where input from both eyes has come together, but where generalization for spatial localization and orientation has not yet occurred.
The Retinotopic Organization of the Human Middle Temporal Area MT/V5 and Its Cortical Neighbors
Together with similarities in retinotopic organization and topological neighborhood, the functional properties suggest that MT/V5 in human and macaque cortex are homologous.
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 area of anaesthetized and paralysed macaque monkeys was studied and suggested that antagonistic surrounds are constructed in MT, probably through horizontal connections, and that a strong vertical organization exists in area MT, as has been shown for V1.
The kinetic occipital (KO) region in man: an fMRI study.
Functional magnetic resonance imaging is used to explore the properties of the kinetic occipital (KO) region, which previous position emission tomography studies have shown to be involved in the processing of kinetic boundaries.
Responses of macaque STS neurons to optic flow components: a comparison of areas MT and MST.
Responses to the three elementary optic flow components (EFCs)--rotation, deformation, and expansion/contraction--and to translation were compared after optimization of stimulus direction, speed, size, and position.
