Visual pathways from the perspective of cost functions and multi-task deep neural networks [PDF]
Vision research has been shaped by the seminal insight that we can understand the higher-tier visual cortex from the perspective of multiple functional pathways with different goals. In this paper, we try to give a computational account of the functional

Decoding Visual Imagery from EEG Signals using Visual Perception Guided Network Training Method [PDF]
An electroencephalogram is an effective approach that provides a bidirectional pathway between user and computer in a non-invasive way. In this study, we adopted the visual perception data for training the visual imagery decoding network. We proposed a visual perception-guided network training approach for decoding visual imagery.

Impaired communication between the dorsal and ventral stream: indications from apraxia
Patients with apraxia perform poorly when demonstrating how an object is used, particularly when pantomiming the action. However, these patients are able to accurately identify, and to pick up and move objects, demonstrating intact ventral and dorsal ...

Developmental Reorganisation of Visual Motion Pathways
In adults, visual form and motion activate independent networks of extrastriate areas which are roughly aligned with the ventral and dorsal streams, respectively.

Vision is a complex function, which is achieved by movements of the eyes to properly foveate targets at any location in 3D space and to continuously refresh neural information in the different visual pathways.

Spatio-Temporally Efficient Coding Assigns Functions to Hierarchical Structures of the Visual System
Hierarchical structures constitute a wide array of brain areas, including the visual system. One of the important questions regarding visual hierarchical structures is to identify computational principles for assigning functions that represent the ...

Brain Differently Changes Its Algorithms in Parallel Processing of Visual Information [PDF]
Feedback from the visual cortex (Vl) to the Lateral Geniculate Nucleus (LGN) in macaque monkey increase contrast gain of LGN neurons for black and white (B&W) and for color (C) stimuli.

A touchy subject: advancing the modulated visual pathways account of altered vision near the hand
A growing body of evidence demonstrates that human vision operates differently in the space near and on the hands; for example, early findings in this literature reported that rapid onsets are detected faster near the hands, and that objects are searched
