Journal ArticleDOI
Functional analysis of primary visual cortex (V1) in humans
Roger B. H. Tootell,Nouchine Hadjikhani,Wim Vanduffel,Arthur K. Liu,Janine D. Mendola,Martin I. Sereno,Anders M. Dale +6 more
TL;DR: Evidence for orientation selectivity in V1 is shown by measuring transient functional MRI increases produced at the change in response to gratings of differing orientations, and the bandwidth of the orientation "transients" is measured.
Journal ArticleDOI
Visual motion processing investigated using contrast agent-enhanced fMRI in awake behaving monkeys
Wim Vanduffel,Denis Fize,Joseph B. Mandeville,Koen Nelissen,Paul Van Hecke,Bruce R. Rosen,Roger B. H. Tootell,Guy Orban +7 more
TL;DR: FMRI signals produced by moving and stationary stimuli (random dots or lines) in fixating monkeys are mapped to clarify the relationship between the motion pathway and the dorsal stream in primates.
Journal ArticleDOI
Deoxyglucose analysis of retinotopic organization in primate striate cortex
TL;DR: The 14C-labeled 2-deoxy-D-glucose method has several advantages over conventional electrophysiological mapping techniques and should prove useful in analyzing retinotopic organization in various visual areas of the brain and in different species.
Journal ArticleDOI
Cortical Mechanisms Specific to Explicit Visual Object Recognition
Moshe Bar,Roger B. H. Tootell,Daniel L. Schacter,Doug Greve,Bruce Fischl,Janine D. Mendola,Bruce R. Rosen,Anders M. Dale +7 more
TL;DR: The cortical mechanisms associated with conscious object recognition were studied using functional magnetic resonance imaging and provide new insights into the processes underlying explicit object recognition, as well as the analysis that takes place immediately before and after recognition.
Journal ArticleDOI
The Representation of Illusory and Real Contours in Human Cortical Visual Areas Revealed by Functional Magnetic Resonance Imaging
TL;DR: Physiological signals obtained from human visual cortex while subjects viewed different types of contours suggest a role in surface perception for this lateral occipital region that includes V3A, V4v, V7, and V8 and finds evidence for overlapping sites of processing.
