Journal ArticleDOI

Kenneth K. Kwong,John W. Belliveau,David A. Chesler,Inna E. Goldberg,Robert M. Weisskoff,Brigitte P. Poncelet,David N. Kennedy,Bernice E. Hoppel,Mark S. Cohen,Robert Turner,Hong-Ming Cheng,Thomas J. Brady,Bruce R. Rosen +12 more
TL;DR: In this paper, a series of images were acquired continuously with the same imaging pulse sequence (either gradient echo or spin-echo inversion recovery) during task activation, and a significant increase in signal intensity (paired t test; P less than 0.001) of 1.8% +/- 0.9% was observed in the primary visual cortex (V1) of seven normal volunteers.
Journal ArticleDOI
Borders of multiple visual areas in humans revealed by functional magnetic resonance imaging
Martin I. Sereno,Anders M. Dale,Anders M. Dale,J. B. Reppas,Kenneth K. Kwong,John W. Belliveau,Thomas J. Brady,Bruce R. Rosen,Roger B. H. Tootell +8 more
TL;DR: Cortical magnification factor curves for striate and extrastriate cortical areas were determined, which showed that human visual areas have a greater emphasis on the center-of-gaze than their counterparts in monkeys.
Journal ArticleDOI
Functional mapping of the human visual cortex by magnetic resonance imaging
John W. Belliveau,David N. Kennedy,Robert C. McKinstry,Bradley R. Buchbinder,Robert M. Weisskoff,Mark S. Cohen,James M. Vevea,Thomas J. Brady,Bruce R. Rosen +8 more
TL;DR: This technique was used to generate the first functional magnetic resonance maps of human task activation, by using a visual stimulus paradigm, and localized increases in blood volume were detected in the primary visual cortex during photic stimulation.
Journal ArticleDOI
Object-related activity revealed by functional magnetic resonance imaging in human occipital cortex.

TL;DR: The lateral occipital complex (LO) showed preferential activation to images of objects, compared to a wide range of texture patterns as mentioned in this paper, suggesting that objects varying widely in their recognizability (e.g., famous faces, common objects, and unfamiliar three-dimensional abstract sculptures) activated it to a similar degree.
Journal ArticleDOI
Functional analysis of human MT and related visual cortical areas using magnetic resonance imaging
Roger B. H. Tootell,J.B. Reppas,Kenneth K. Kwong,Rafael Malach,Richard T. Born,Thomas J. Brady,Bruce R. Rosen,John W. Belliveau +7 more
TL;DR: FMRI activity in human MT does in fact decrease at and near individually measured equiluminance, and area MT has a much higher contrast sensitivity than that in several other areas, including primary visual cortex (V1).
