The functional architecture of the object vision pathway in the human brain was investigated using functional magnetic resonance imaging to measure patterns of response in ventral temporal cortex… Expand
Effective connectivity within the distributed cortical network for face perception.
This work found that the core system is hierarchically organized in a predominantly feed-forward fashion, and that the fusiform gyrus (FG) exerts the dominant influence on the extended system, whereas famous faces increased the coupling between the FG and the orbitofrontal cortex. Expand
Face perception is mediated by a distributed cortical network
Results indicate that a mere percept of a face is sufficient to localize activation within the distributed cortical network that mediates the visual analysis of facial identity and expression. Expand

It is proposed that the functional architecture of the ventral visual pathway is not a mosaic of category-specific modules but instead is a continuous representation of information about object form that has a highly consistent and orderly topological arrangement. Expand
Let’s face it: It’s a cortical network

Analysis of effective connectivity reveals that the major entry node in the "face network" is the lateral fusiform gyrus and that the functional coupling between the core and the extended systems is content-dependent. Expand
Where bottom-up meets top-down: neuronal interactions during perception and imagery.
This investigation revealed that neuronal interactions between occipito-temporal, parietal and frontal regions are task- and stimulus-dependent and mediated by content-sensitive forward connections from early visual areas. Expand
Distributed neural systems for the generation of visual images

Findings suggest that the medial orbitofrontal cortex (OFC) represents the value of salient sexually-relevant faces, irrespective of their reproductive fitness. Expand
Face Perception Is Modulated by Sexual Preference
The findings suggest that sexual preference modulates face-evoked activation in the reward circuitry, and a significant interaction between stimulus gender and the sexual preference of the subject in the thalamus and medial orbitofrontal cortex is found. Expand
Distributed Neural Systems for the Generation of Visual Images
The results suggest that content-related activation during imagery in visual extrastriate cortex may be implemented by "top-down" mechanisms in parietal and frontal cortex that mediate the retrieval of face and object representations from long-term memory and their maintenance through visual imagery.
