Let's face it: It's a cortical network
Face perception elicits activation within a distributed cortical network in the human brain. The network includes visual ("core") regions, which process invariant facial features, as well as limbic and prefrontal ("extended") regions that process changeable aspects of faces. Analysis of effective connectivity reveals that the major entry node in the "face network" is the lateral fusiform gyrus ...
متن کاملThe neuropsychology of face perception: beyond simple dissociations and functional selectivity.
Face processing relies on a distributed, patchy network of cortical regions in the temporal and frontal lobes that respond disproportionately to face stimuli, other cortical regions that are not even primarily visual (such as somatosensory cortex), and subcortical structures such as the amygdala. Higher-level face perception abilities, such as judging identity, emotion and trustworthiness, appe...
متن کاملNetwork dynamics of human face perception
Prevailing theories suggests that cortical regions responsible for face perception operate in a serial, feed-forward fashion. Here, we utilize invasive human electrophysiology to evaluate serial models of face-processing via measurements of cortical activation, functional connectivity, and cortico-cortical evoked potentials. We find that task-dependent changes in functional connectivity between...
متن کاملThe Face Network: Overextended? (Comment on: "Let's face it: It's a cortical network" by Alumit Ishai)
We offer a critique of Ishai's [Ishai, A., 2008. Let's face it: it's a cortical network. NeuroImage. doi:10.1016/j.neuroimage.2007.10.040] comment on the value of considering the brain areas that support face perception as a network. We emphasise that this idea is not in opposition to the notion that the fusiform gyrus plays a key role in the visual analysis of faces. More important, we argue t...
متن کاملFace perception is mediated by a distributed cortical network.
The neural system associated with face perception in the human brain was investigated using functional magnetic resonance imaging (fMRI). In contrast to many studies that focused on discreet face-responsive regions, the objective of the current study was to demonstrate that regardless of stimulus format, emotional valence, or task demands, face perception evokes activation in a distributed cort...
