Journal ArticleDOI
Faces and objects in macaque cerebral cortex.
Doris Y. Tsao,Winrich A. Freiwald,Winrich A. Freiwald,T. Knutsen,Joseph B. Mandeville,Roger B. H. Tootell +5 more
TL;DR: It is found that macaques do have discrete face-selective patches, similar in relative size and number to face patches in humans, and these results suggest that humans and macaques share a similar brain architecture for visual object processing.
Journal ArticleDOI
Functional anatomy of macaque striate cortex. II. Retinotopic organization.
TL;DR: In the central half of V1, the cortical magnification was found to be greater along the vertical than along the horizontal meridian, and overall magnification factors appeared to be scaled proportionate to brain size across different species.
Journal ArticleDOI
Functional anatomy of macaque striate cortex. III. Color
TL;DR: The DG results suggest that color sensitivity is also high in the lower-layer (layers 5 + 6) blobs, and that many layer 5 receptive fields are double-opponent, which supports the idea of a color-insensitive stream running from the magnocellular LGN layers through striate layers 4Ca and 4B to extrastriate areas MT and V3.
Journal ArticleDOI
Retinotopy and color sensitivity in human visual cortical area V8.
TL;DR: The location of the human color-selective region did not match the location of area V4 (neither its dorsal nor ventral subdivisions), as extrapolated from macaque maps, and instead this region coincides with a new retinotopic area that is called 'V8', which includes a distinct representation of the fovea and both upper and lower visual fields.
Journal ArticleDOI
Cortical fMRI activation produced by attentive tracking of moving targets
Jody C. Culham,Stephan A. Brandt,Stephan A. Brandt,Patrick Cavanagh,Nancy Kanwisher,Anders M. Dale,Roger B. H. Tootell +6 more
TL;DR: FMRI results suggest that attentive tracking is mediated by a network of areas that includes parietal and frontal regions responsible for attention shifts and eye movements and the MT complex, thought to be responsible for motion perception.
