Distributed and Overlapping Representations of Faces and Objects in Ventral Temporal Cortex

J. V. Haxby
2001 Science  
These results indicate that the representations of faces and objects in ventral temporal cortex are widely distributed and overlapping.  ...  We tested our model by investigating the patterns of response evoked in ventral temporal cortex by faces and multiple categories of objects.  ...  These results indicate that the representations of faces and objects in ventral temporal cortex are widely distributed and overlapping.  ...

Similarity-Based Fusion of MEG and fMRI Reveals Spatio-Temporal Dynamics in Human Cortex During Visual Object Recognition

Radoslaw Martin Cichy, Dimitrios Pantazis, Aude Oliva
2016 Cerebral Cortex  
Further region-of-interest analyses established that dorsal and ventral regions showed MEG-fMRI correspondence in representations later than early visual cortex.  ...  Every human cognitive function, such as visual object recognition, is realized in a complex spatio-temporal activity pattern in the brain.  ...  Conflict of Interest: None declared.  ...

The functional architecture of the ventral temporal cortex and its role in categorization

Kalanit Grill-Spector, Kevin S. Weiner
2014 Nature Reviews Neuroscience  
| Visual categorization is thought to occur in the human ventral temporal cortex (VTC), but how this categorization is achieved is still largely unknown.  ...  In this Review, we consider the computations and representations that are necessary for categorization and examine how the microanatomical and macroanatomical layout of the VTC might optimize them to achieve  ...  Jacques for creating figure 2b, and N.

The representation of information about faces in the temporal and frontal lobes

2007 Neuropsychologia  
Another population of neurons in the cortex in the superior temporal sulcus encodes other aspects of faces such as face expression, eye gaze, face view and whether the head is moving.  ...  Which face or object is present is encoded using a distributed representation in which each neuron conveys independent information in its firing rate, with little information evident in the relative time  ...  Acknowledgements The author has worked on some of the investigations described here with P.
