Multivariate patterns in object-selective cortex dissociate perceptual and physical shape similarity

J Haushofer, MS Livingstone, N Kanwisher - PLoS biology, 2008 - journals.plos.org
Prior research has identified the lateral occipital complex (LOC) as a critical cortical region
for the representation of object shape in humans. However, little is known about the nature …

Different spatial scales of shape similarity representation in lateral and ventral LOC

DM Drucker, GK Aguirre - Cerebral Cortex, 2009 - academic.oup.com
We investigated the relationship between stimulus similarity for a set of parameterized
shapes and the spatial scale of neural representation within subregions of the lateral …

Representation of the perceived 3-D object shape in the human lateral occipital complex

Z Kourtzi, M Erb, W Grodd, HH Bülthoff - Cerebral cortex, 2003 - academic.oup.com
We used human functional magnetic resonance imaging (fMRI) to test whether the human
lateral occipital complex (LOC), an area known to be involved in the analysis of visual …

Perceived shape similarity among unfamiliar objects and the organization of the human object vision pathway

HPO de Beeck, K Torfs, J Wagemans - Journal of Neuroscience, 2008 - Soc Neuroscience
Humans rely heavily on shape similarity among objects for object categorization and
identification. Studies using functional magnetic resonance imaging (fMRI) have shown that …

Multivariate patterns in the human object-processing pathway reveal a shift from retinotopic to shape curvature representations in lateral occipital areas, LO-1 and LO …

RJW Vernon, AD Gouws, SJD Lawrence… - Journal of …, 2016 - Soc Neuroscience
Representations in early visual areas are organized on the basis of retinotopy, but this
organizational principle appears to lose prominence in the extrastriate cortex. Nevertheless …

Cortical regions involved in perceiving object shape

Z Kourtzi, N Kanwisher - Journal of Neuroscience, 2000 - Soc Neuroscience
The studies described here use functional magnetic resonance imaging to test whether
common or distinct cognitive and/or neural mechanisms are involved in extracting object …

Shape saliency modulates contextual processing in the human lateral occipital complex

CF Altmann, A Deubelius… - Journal of Cognitive …, 2004 - ieeexplore.ieee.org
Visual context influences our perception of target objects in natural scenes. However, little is
known about the analysis of context information and its role in shape perception in the …

Nonvisual and visual object shape representations in occipitotemporal cortex: evidence from congenitally blind and sighted adults

MV Peelen, C He, Z Han, A Caramazza… - Journal of …, 2014 - Soc Neuroscience
Knowledge of object shape is primarily acquired through the visual modality but can also be
acquired through other sensory modalities. In the present study, we investigated the …

Separate processing of texture and form in the ventral stream: evidence from FMRI and visual agnosia

C Cavina-Pratesi, RW Kentridge, CA Heywood… - Cerebral …, 2010 - academic.oup.com
Real-life visual object recognition requires the processing of more than just geometric
(shape, size, and orientation) properties. Surface properties such as color and texture are …

Representation of shapes, edges, and surfaces across multiple cues in the human visual cortex

J Vinberg, K Grill-Spector - Journal of neurophysiology, 2008 - journals.physiology.org
The lateral occipital complex (LOC) responds preferentially to objects compared with
random stimuli or textures independent of the visual cue. However, it is unknown whether …
