A Cortical Area Selective for Visual Processing of the Human Body
A series of functional magnetic resonance imaging studies revealing substantial evidence for a distinct cortical region in humans that responds selectively to images of the human body, as compared with a wide range of control stimuli.
Selectivity for the human body in the fusiform gyrus.
Functional neuroimaging studies have revealed human brain regions, notably in the fusiform gyrus, that respond selectively to images of faces as opposed to other kinds of objects. Here we use fMRI to…
Interactions Between Visual Working Memory and Selective Attention

Results confirm a specific prediction about the influence of working memory contents on the guidance of attention, and generalized across object type, attentional-probe task, and working memory task.
The neural basis of visual body perception
Evidence from studies of both humans and non-human primates points to focal regions of the higher-level visual cortex that are specialized for the visual perception of the body that have been implicated in the Perception of the self and the 'body schema', the perception of others' emotions and the understanding of actions.
fMRI evidence for objects as the units of attentional selection
Functional magnetic resonance imaging (fMRI) is used to test key predictions of the object-based theory, which proposes that pre-attentive mechanisms segment the visual array into discrete objects, groups, or surfaces, which serve as targets for visual attention.

The broadest survey to date of category selectivity in visual cortex, 12 participants were scanned with functional magnetic resonance imaging while viewing scenes and 19 different object categories in a blocked-design experiment found selectivity for faces in the fusiform face area, for scenes in the parahippocampal place area (PPA), and for bodies in the extrastriate body area (EBA).
Competition in visual working memory for control of search
Results are consistent with two general models: One in which a representation of the current task biases the competition between items in a unitary VWM, or one in which VWM is fractionated to allow for maintenance of critical items that are not immediately relevant to the task.
Functional MRI analysis of body and body part representations in the extrastriate and fusiform body areas.
It is hypothesized that the EBA analyzes bodies at the level of parts (as has been proposed for faces in the OFA), whereas FBA (by analogy to FFA) may have a role in processing the configuration of body parts into wholes.
