متن کاملThe cortical visual area V6 in macaque and human brains.
Single cell recording and neuro-anatomical techniques in the monkey have allowed to find a mosaic of visual areas in the temporo-parieto-occipital cortex. Thanks to neuroimaging methods, several of these areas have been mapped also in the human brain and named in humans based on homologies in their visuotopic organization with non-human primate areas. We have recently found a new, retinotopical...
متن کاملSensitivity of human visual cortical area V6 to stereoscopic depth gradients associated with self-motion
The principal visual cue to self-motion (egomotion) is optic flow, which is specified in terms of local 2D velocities in the retinal image without reference to depth cues. However, in general, points near the center of expansion of natural flow fields are distant, whereas those in the periphery are closer, creating gradients of horizontal binocular disparity. To assess whether the brain combine...
متن کاملThe cortical connections of area V6: an occipito-parietal network processing visual information.
The aim of this work was to study the cortical connections of area V6 by injecting neuronal tracers into different retinotopic representations of this area. To this purpose, we first functionally recognized V6 by recording from neurons of the parieto-occipital cortex in awake macaque monkeys. Penetrations with recording syringes were performed in the behaving animals in order to inject tracers ...
متن کاملHuman V6: The Medial Motion Area
Cortical-surface-based functional Magnetic Resonance Imaging mapping techniques and wide-field retinotopic stimulation were used to verify the presence of pattern motion sensitivity in human area V6. Area V6 is highly selective for coherently moving fields of dots, both at individual and group levels and even with a visual stimulus of standard size. This stimulus is a functional localizer for V...
