Redundant neural vision systems: competing for collision recognition roles [PDF]

open access: yes, 2013
Ability to detect collisions is vital for future robots that interact with humans in complex visual environments. Lobula giant movement detectors (LGMD) and directional selective neurons (DSNs) are two types of identified neurons found in the visual ...

Visual Pathways Serving Motion Detection in the Mammalian Brain

open access: yesSensors, 2010
Motion perception is the process through which one gathers information on the dynamic visual world, in terms of the speed and movement direction of its elements.

A Dual-Stream Neural Network Explains the Functional Segregation of Dorsal and Ventral Visual Pathways in Human Brains [PDF]

open access: yesarXiv, 2023
The human visual system uses two parallel pathways for spatial processing and object recognition. In contrast, computer vision systems tend to use a single feedforward pathway, rendering them less robust, adaptive, or efficient than human vision. To bridge this gap, we developed a dual-stream vision model inspired by the human eyes and brain.

Visual and eye movement functions of the posterior parietal cortex [PDF]

open access: yes, 1989
Lesions of the posterior parietal area in humans produce interesting spatial-perceptual and spatial-behavioral deficits. Among the more important deficits observed are loss of spatial memories, problems representing spatial relations in models or ...

Visual control of flight speed in Drosophila melanogaster [PDF]

open access: yes, 2009
Flight control in insects depends on self-induced image motion (optic flow), which the visual system must process to generate appropriate corrective steering maneuvers.

Direct neural pathways convey distinct visual information to Drosophila mushroom bodies

open access: yeseLife, 2016
Previously, we demonstrated that visual and olfactory associative memories of Drosophila share mushroom body (MB) circuits (Vogt et al., 2014). Unlike for odor representation, the MB circuit for visual information has not been characterized.

Visual Modeling Languages in Patient Pathways: Scoping Review

open access: yesInteractive Journal of Medical Research
BackgroundPatient pathways (PPs) are presented as a panacea solution to enhance health system functions. It is a complex concept that needs to be described and communicated well.

Parallel neural pathways in higher visual centers of the Drosophila brain that mediate wavelength-specific behavior

open access: yesFrontiers in Neural Circuits, 2014
Compared with connections between the retinae and primary visual centers, relatively less is known in both mammals and insects about the functional segregation of neural pathways connecting primary and higher centers of the visual processing cascade ...

Multiple Sensory-Motor Pathways Lead to Coordinated Visual Attention.

open access: yesCognitive Sciences, 2017
Joint attention has been extensively studied in the developmental literature because of overwhelming evidence that the ability to socially coordinate visual attention to an object is essential to healthy developmental outcomes, including language ...

Modulation of connectivity in visual pathways by attention: cortical interactions evaluated with structural equation modelling and fMRI.

open access: yesCerebral Cortex, 1997
Electrophysiological and neuroimaging studies have shown that attention to visual motion can increase the responsiveness of the motion-selective cortical area V5 and the posterior parietal cortex (PP). Increased or decreased activation in a cortical area
