Journal ArticleDOI
Spatiotemporal activity of a cortical network for processing visual motion revealed by MEG and fMRI.
Seppo P. Ahlfors,G. V. Simpson,Anders M. Dale,John W. Belliveau,A.K. Liu,Antti Korvenoja,Juha Virtanen,Juha Virtanen,Minna Huotilainen,Minna Huotilainen,Roger B. H. Tootell,Hannu J. Aronen,Risto J. Ilmoniemi +12 more
TL;DR: Characteristic patterns of activity are revealed in this cortical network for processing sudden changes in the direction of visual motion in motion sensitive areas of the brain.
Journal ArticleDOI
Repeated fMRI using iron oxide contrast agent in awake, behaving macaques at 3 Tesla.
F. Leite,Doris Y. Tsao,Wim Vanduffel,Denis Fize,Yuka Sasaki,Lawrence L. Wald,Anders M. Dale,Kenneth K. Kwong,Guy Orban,Bruce R. Rosen,Roger B. H. Tootell,Joseph B. Mandeville +11 more
TL;DR: The contrast agent MION produced a dramatic improvement in functional brain imaging results in the awake, behaving primate at this field strength, compared to BOLD imaging at 3 Tesla.
Journal ArticleDOI
Scene-Selective Cortical Regions in Human and Nonhuman Primates
Shahin Nasr,Ning Liu,Kathryn J. Devaney,Xiaomin Yue,Reza Rajimehr,Leslie G. Ungerleider,Roger B. H. Tootell +6 more
TL;DR: A homologous neural architecture for scene- selective regions in visual cortex of humans and nonhuman primates, analogous to the face-selective regions demonstrated earlier in these two species are suggested.
Journal ArticleDOI
Functional anatomy of macaque striate cortex. IV. Contrast and magno- parvo streams
TL;DR: The sum of all available evidence suggests that the magnocellular information projects strongly through striate layers 4Ca, 4B, and 6, with moderate input into the blobs in layers 2 + 3, and to blob-aligned portions of layer 4A, which is essentially saturated at stimulus contrasts of 50% and above.
Journal ArticleDOI
Functional anatomy of macaque striate cortex. V. Spatial frequency
TL;DR: Variations in uptake between layers 4Ca and 4Cb, as a function of eccentricity, shift in parallel with the changes in the upper-layer topography, which is consistent with known, eccentricity-dependent variations of receptive-field size and spatial frequency tuning.
