Journal ArticleDOI

High-resolution intersubject averaging and a coordinate system for the cortical surface.

TL;DR: This work has developed a means for generating an average folding pattern across a large number of individual subjects as a function on the unit sphere and of nonrigidly aligning each individual with the average, establishing a spherical surface‐based coordinate system that is adapted to the folding pattern of each individual subject, allowing for much higher localization accuracy of structural and functional features of the human brain.
Journal ArticleDOI

Borders of multiple visual areas in humans revealed by functional magnetic resonance imaging

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

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

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).
Journal ArticleDOI

Mechanisms of migraine aura revealed by functional MRI in human visual cortex

TL;DR: High-field functional MRI with near-continuous recording during visual aura in three subjects observed blood oxygenation level-dependent signal changes that strongly suggest that an electrophysiological event such as CSD generates the aura in human visual cortex.
