The dorsal visual pathway represents object-centered spatial relations for object recognition
- Biology, PsychologybioRxiv
It is suggested that dorsal cortex is a crucial source of input to the ventral pathway and may support the ability to categorize objects on the basis of global shape, and shed light on the broader network of brain regions that support object categorization.

Visual Object Processing

We present an overview of the functional and anatomical pathways and steps involved in going from a pattern of photoreceptor activations in the retina to recognizing an object in the world. Our focus…

Investigating the Interaction Between Form and Motion Processing: A Review of Basic Research and Clinical Evidence
- Biology, PsychologyFrontiers in Psychology
An update of the neurophysiological, brain imaging, psychophysical, clinical, and brain stimulation studies which have assessed form and motion integration mechanisms, and the level at which this occurs in the human and non-human primate brain is shown.
What Does Dorsal Cortex Contribute to Perception?
- Biology, PsychologyOpen Mind
Evidence is presented that the dorsal pathway contributes uniquely to the perception of a range of visuospatial attributes that are not redundant with representations in ventral cortex, and it is proposed that dorsal cortex may selectively process visual attributes that can inform the Perception of potential actions on objects and environments.
The Neural Dynamics of Seeing-In
- Psychology, PhilosophyErkenntnis
Philosophers have suggested that, in order to understand the particular visual state we are in during picture perception, we should focus on experimental results from vision neuroscience—in…
Specialization of mid-tier stages of dorsal and ventral pathways in stereoscopic processing
A novel tradeoff is reported where MT neurons transmit disparity signals quickly and robustly, whereas V4 neurons markedly transform the nature of the signals with extra time to solve the stereo correspondence problem, suggesting signaling speed and robustness are traded for computational complexity.
Feature integration and object representations along the dorsal stream visual hierarchy
- BiologyFront. Comput. Neurosci.
This work reviews the hierarchical processing of motion along the dorsal stream and the building up of object representations along the ventral stream, and proposes a framework describing how and at what stage different features are integrated into dorsal visual stream object representations.

Dorsal–Ventral Integration in the Recognition of Motion-Defined Unfamiliar Faces
- Psychology, BiologyThe Journal of Neuroscience
Three-dimensional structure-from-motion cues, thought to be computed exclusively by dorsal stream mechanisms, are sufficient to drive complex object recognition and that ventral stream areas are necessary for both identification and learning of unfamiliar faces from SFM cues are suggested.
Comparison of shape encoding in primate dorsal and ventral visual pathways.
- Biology, PsychologyJournal of neurophysiology
Differences in the two visual pathways provide the first neurophysiological evidence that shape encoding in the dorsal pathway is distinct from and not a mere duplication of that formed in the ventral pathway.
Two hierarchically organized neural systems for object information in human visual cortex
- Biology, PsychologyNature Neuroscience
These findings indicate that basic object information related to shape, size and viewpoint may be represented similarly in two parallel and hierarchically organized neural systems in the ventral and dorsal visual pathways.
Shape selectivity in primate lateral intraparietal cortex
- Biology, PsychologyNature
It is shown that many neurons in primate posterior parietal cortex show sensory shape selectivities to simple, two-dimensional geometric shapes while the animal performs a simple fixation task, and these units show shape selectivity equivalent to any shown in the ventral pathway.

Shape‐selective stereo processing in human object‐related visual areas
- Psychology, BiologyHuman brain mapping
The results reveal shape selective activation from images of objects defined purely by stereoscopic cues in the human ventral stream, and show a significant correlation between recognition and fMRI signal in the object‐related occipito‐temporal cortex (lateral occipital complex).
View-invariant representations of familiar objects by neurons in the inferior temporal visual cortex.
- Biology, PsychologyCerebral cortex
A population of single neurons in the temporal visual cortex that have view-invariant representations of familiar objects are described, and the coding scheme was shown to be sparse distributed, with relatively independent information being provided by the different neurons.
Visual object recognition: do we know more now than we did 20 years ago?

The field is still faced with the challenge of developing a comprehensive theory that integrates this ever-increasing body of results and explains how the authors perceive and recognize objects.
