How a visual stimulus is initially categorized as a face by the cortical face-processing network remains largely unclear. In this study we used functional MRI to study the dynamics of face detection in visual scenes by using a paradigm in which scenes containing faces or cars are revealed progressively as they emerge from visual noise. Participants were asked to respond as soon as they detected a face or car during the noise sequence. Among the face-sensitive regions identified based on a…

Category search speeds up face-selective fMRI responses in a non-hierarchical cortical face network

Being BOLD: The neural dynamics of face perception

TLDR
The results support the non‐hierarchical view of human cortical face processing and open new perspectives for time‐resolved analysis at the single subject level of fMRI data obtained during continuously evolving visual stimulation.

The Hierarchical Brain Network for Face Recognition

TLDR
This study uses fMRI to identify face-selective regions in the entire brain and explores the hierarchical structure of the face-processing network by analyzing functional connectivity among these regions, helping elucidate the neural mechanisms underlying face recognition at the network level.

The occipital face area is causally involved in identity-related visual-semantic associations

TLDR
It is found that the stimulation of the right or left OFA reduced subsequent retrieval performance for the face-associated job titles, suggesting a causal role of the OFA in the association of faces and related semantic information.

Holistic Face Categorization in Higher Order Visual Areas of the Normal and Prosopagnosic Brain: Toward a Non-Hierarchical View of Face Perception

TLDR
It is tested in fMRI with visual stimuli that are categorized as faces based on their global configuration rather than their local parts, supporting a non-hierarchical view of face perception in the visual cortex and indicating that face-preferential activation may emerge in higher order visual areas of the right hemisphere without any face- Preferential inputs from lower ordervisual areas.

The fusiform face area subserves face perception, not generic within-category identification

TLDR
The results indicate that the FFA is involved in both detection and identification of faces, but that it has little involvement in within-category identification of non-face objects (including objects of expertise).

Detecting faces in pure noise images: a functional MRI study on top-down perception

TLDR
Across participants, positive correlations were found for the degree of greater face-detection activation between the fusiform face area and bilateral inferior frontal gyri, suggesting a top-down pathway generating perceptual expectations.

A network of occipito-temporal face-sensitive areas besides the right middle fusiform gyrus is necessary for normal face processing.

TLDR
Findings show that the integrity of the right OFA is necessary for normal face perception and suggest that the face-sensitive responses observed at this level in normal subjects may arise from feedback connections from the right FFA.

Faces are represented holistically in the human occipito-temporal cortex

Top-down activation of fusiform cortex without seeing faces in prosopagnosia.

TLDR
It is revealed that fusiform activation is still selectively modulated by task demands related to the anticipation of a face, despite severe face-recognition deficits and the fact that no reliable stimulus-driven response is evoked by actual facial information.

Location of human face‐selective cortex with respect to retinotopic areas

TLDR
It is concluded that the fusiform face area in humans lies in non‐retinotopic visual association cortex of the ventral form‐processing stream, in an area that may be roughly homologous in location to area TF or CITv in monkeys.

An anterior temporal face patch in human cortex, predicted by macaque maps

Increasing evidence suggests that primate visual cortex has a specialized architecture for processing discrete object categories such as faces. Human fMRI studies have described a localized region in

The initial representation of individual faces in the right occipito-temporal cortex is holistic: electrophysiological evidence from the composite face illusion.

TLDR
Recording event-related potentials during an adaptation paradigm of the composite face illusion indicates that the earliest perceptual representation of an individual face in the human brain is holistic rather than based on independent face parts.
