The existence and neuroanatomical locations of separate extrastriate visual pathways for object recognition and spatial localization were investigated in healthy young men. Regional cerebral blood flow was measured by positron emission tomography and bolus injections of H2(15)O, while subjects performed face matching, dot-location matching, or sensorimotor control tasks. Both visual matching tasks activated lateral occipital cortex. Face discrimination alone activated a region of…

The functional organization of human extrastriate cortex: a PET-rCBF study of selective attention to faces and locations

The functional dissociation of human extrastriate cortical processing streams for the perception of face identity and location was investigated in healthy men by measuring visual task-related changes

Functional Associations among Human Posterior Extrastriate Brain Regions during Object and Spatial Vision

Correlations between normalized regional cerebral blood flow values were used to examine functional associations among posterior brain regions for these two pathways in 17 young men during performance of a face matching task and a dot-location matching task to suggest correlational analysis of normalized rCBF can detect functional interactions between components of proposed brain circuits.

Dissociation of Object and Spatial Vision in Human Extrastriate Cortex: Age-Related Changes in Activation of Regional Cerebral Blood Flow Measured with [15 O]Water and Positron Emission Tomography

Results show less functional separation of the dorsal and ventral visual pathways in older subjects, and may reflect an age-related reduction in the processing efficiency of these visual cortical areas.

Visual exploration of form and position with identical stimuli: Functional anatomy with PET

Although the visual stimuli were identical, the network of activated cortical fields depended on whether the task was a form discrimination task or a position discrimination task, indicating a strong task dependence of cortical networks underlying form and position discrimination in the human brain.

Neural Mechanisms of Visual Attention: Object-Based Selection of a Region in Space

Objects play an important role in guiding spatial attention through a cluttered visual environment. We used event-related functional magnetic resonance imaging (ER-fMRI) to measure brain activity



Occipital cortex in man: Organization of callosal connections, related myelo‐ and cytoarchitecture, and putative boundaries of functional visual areas

The pattern of callosal afferents in (human) areas 17, 18, and 19 as well as their cortical architecture are described and the position of some visual areas is inferred.

The Relationship between Global and Local Changes in PET Scans

It is shown that the increase in activity due to a cognitive activation is independent of global activity, with the “nuisance” variable as global activity and the activation condition as the categorical independent variable for an analysis of covariance.

Localisation in PET Images: Direct Fitting of the Intercommissural (AC—PC) Line

A technique is described for estimating the position of the intercommisural line (AC–PC line) directly from landmarks on positron emission tomographic images, namely the ventral aspects of the anterior and posterior corpus callosum, the thalamus, and occipital pole, which showed minimal vertical and angular displacement when measured on magnetic resonance imaging (MRI) scans.

This report describes an approach that may partially resolve the uncertainty in assessing the significance of statistical parametric maps and models the SPM as a stationary stochastic process.

A strategy for measurement of regional CBF that rigorously accounts for differing tracer partition coefficients and recirculation is described, and is convenient for use with positron emission tomography.

Plastic transformation of PET images.

A theory and technique are presented that allow nonlinear resampling of positron emission tomography data to remove nonlinear differences in brain shape. The resampling is determined empirically by a

Attentional modulation of neural processing of shape, color, and velocity in humans.

Psychophysical evidence indicated that the sensitivity for discriminating subtle stimulus changes was higher when subjects focused attention on one attribute than when they divided attention among several attributes.
