Pattern Separation in the Ventral Visual Stream
… inputs into less overlapping outputs. In the ventral visual stream (VVS) there is considerable evidence for hierarchical transformation from feature-based visual representations to conjunctive whole-object representations, with the latter allowing for distinct coding even when objects have …

How does the primate ventral visual stream causally support core object recognition?
… perform the computationally difficult visual task of invariant object recognition - the ability to discriminate between different objects in the face of high variation in object viewing parameters and background conditions. This ability is thought to rely on the ventral visual stream, a …

Evaluating ventral visual stream contributions to human visual robustness with deep learning approaches
The human visual system exhibits remarkable robustness, allowing resilient object recognition despite noisy and ambiguous sensory inputs. Such perceptual invariance has been proposed to stem from hierarchical computations along the ventral visual stream (VVS), a series of brain regions that …

Topographic deep artificial neural network as a model of primate ventral visual stream
Face processing in visual cortex has been widely studied and emphasized for its importance in primate survival and social communication. Monkey inferior temporal (IT) cortex contains neurons that respond preferentially to faces and cluster into several regions ("face patches") that together are …

Unsupervised learning of invariant object representation in primate visual cortex
Visual object recognition (categorization and identification) is one of the most fundamental cognitive functions for our survival. Our visual system has the remarkable ability to convey to us visual object and category information in a manner that is largely tolerant ("invariant") to the exact …

High-level visual object representation in juvenile and adult primates
… These computations are thought to reside in the ventral visual stream, specifically culminating in inferior temporal (IT) cortex. Recent research in machine learning has made great progress in modeling primate ventral visual stream computations. While the end result of current machine learning …

Roles of the Dorsal and Ventral Visual Streams In Fluent Reading
… reading literature on phonological awareness, visual deficits have also been observed in disabled readers. Visual processing has been shown to be abnormal in individuals with dyslexia (e.g., Eden et al., 1996), specifically in the dorsal visual stream of the brain, which processes motion. It is …

Decoding the emotional modulation of memory encoding: a multivariate fmri study of arousal and valence
… with key informative regions localised to the ventral visual stream and temporal memory systems, including the inferior temporal and fusiform gyri. In contrast, while we identified distinct neural patterns for memory encoding under different valence conditions, their decoding accuracies did not …

The neural and psychophysical bases of memorability
… to memorability in the medial temporal lobe and ventral visual stream, with a memorability-centric representational geometry in the neural patterns in these regions. Importantly, this sensitivity is dissociable from classical individual subsequent memory effects that I show to be localized in the …

The connectivity fingerprints of the frontal eye field and the inferior frontal junction
… in the control of spatial versus non-spatial visual processing, respectively, and hypothesized that their connectivity fingerprints might underlie these roles. To accurately infer the localization of these regions in standard space, I carried out an activation likelihood estimation (ALE) fMRI …

Action and rehabilitation in hemispatial neglect
… structure that receives input from the ventral visual stream, but not from the dorsal-stream. Consequently, they postulate that neglect patients should code spatial parameters for action veridically. Another strong claim of the model is that the dorsal stream’s control of action is …

Getting a grip on Schizotypy: Elucidating dorsal stream deficits in Schizophrenia Spectrum Disorders
… are associated with disproportionate dorsal visual stream dysfunction, relative to ventral visual stream function. However, there remains a gap in our understanding of the neuropsychology and functional implications of this deficit. Notably, the balance of evidence implicating dorsal stream …
