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
TLDR
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.
Double dissociation in neural correlates of visual working memory: a PET study.
TLDR
The results support the existence of a domain-specific dissociation with dorsal and ventral cortical systems involved respectively in spatial and non spatial working memory functions.
Mapping multiple visual areas in the human brain with a short fMRI sequence
TLDR
The short stimulus sequence robustly invoked multiple visual areas and can be used to map the organization of the visual system in normal and brain-damaged individuals.

The purpose of this review is to: (1) compare and contrast the relative contributions that the four principle regions in cat extrastriate parietal cortex make to a battery of visual tasks which
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
TLDR
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
TLDR
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.
Cross-modal activation of visual cortex during depth perception using auditory substitution of vision
TLDR
Activation foci were found in visual association areas during both the target search task, which recruited the occipito-parietal cortex, and the depth perception task,Which indicates that some brain areas of the visual cortex are relatively multimodal and may be recruited for depth processing via a sense other than vision.
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

A direct demonstration of functional specialization in human visual cortex
TLDR
PET is used to demonstrate directly the specialization of function in the normal human visual cortex, and provides direct evidence to show that, just as in the macaque monkey, different areas of the human prestriate visual cortex are specialized for different attributes of vision.
Occipital cortex in man: Organization of callosal connections, related myelo‐ and cytoarchitecture, and putative boundaries of functional visual areas
TLDR
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.
Attentional modulation of neural processing of shape, color, and velocity in humans.
TLDR
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.
The Relationship between Global and Local Changes in PET Scans
TLDR
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.
Dissociable visual and spatial impairments following right posterior cerebral lesions: Clinical, neuropsychological and anatomical evidence
TLDR
The clinical, neuropsychological and post-mortem anatomical data are considered in relation to evidence from physiological research of two major cortico-cortical pathways for object-recognition and spatial perception.
Localisation in PET Images: Direct Fitting of the Intercommissural (AC—PC) Line
TLDR
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.
Comparing Functional (PET) Images: The Assessment of Significant Change
TLDR
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.

TLDR
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.
