The cat primary visual cortex /

open access: yes, 2002
Written by experts on the forefront of investigations of brain function, vision, and perception, the material presented is of an unparalleled scientific quality, and shows that analyses of enormous breadth and sophistication are required to probe the ...

MEG reveals a fast pathway from somatosensory cortex to occipital areas via posterior parietal cortex in a blind subject

open access: yesFrontiers in Human Neuroscience, 2013
Cross-modal activity in visual cortex of blind subjects has been reported during performance of variety of non-visual tasks. A key unanswered question is through which pathways non-visual inputs are funneled to the visual cortex. Here we used tomographic

Experience-Dependent Development and Maintenance of Binocular Neurons in the Mouse Visual Cortex

open access: yesCell Reports, 2020
Summary: The development of neuronal circuits requires both hard-wired gene expression and experience-dependent plasticity. Sensory processing, such as binocular vision, is especially sensitive to perturbations of experience.

Distributed fading memory for stimulus properties in the primary visual cortex [PDF]

open access: yes, 2009
It is currently not known how distributed neuronal responses in early visual areas carry stimulus-related information. We made multielectrode recordings from cat primary visual cortex and applied methods from machine learning in order to analyze the ...

Postnatal development of intrinsic and synaptic properties transforms signaling in the Layer 5 excitatory neural network of the visual cortex [PDF]

open access: yes, 2011
Information flow in neocortical circuits is regulated by two key parameters: intrinsic neuronal properties and the short-term activity-dependent plasticity of synaptic transmission.

Psychophysical tests of the hypothesis of a bottom-up saliency map in primary visual cortex [PDF]

open access: yes, 2007
A unique vertical bar among horizontal bars is salient and pops out perceptually. Physiological data have suggested that mechanisms in the primary visual cortex (V1) contribute to the high saliency of such a unique basic feature, but indicated little ...

Exploring BOLD changes during spatial attention in non-stimulated visual cortex [PDF]

open access: yes, 2009
Blood oxygen level-dependent (BOLD) responses were measured in parts of primary visual cortex that represented unstimulated visual field regions at different distances from a stimulated central target location.

Coordinated optimization of visual cortical maps : 2. Numerical studies [PDF]

open access: yes, 2012
In the juvenile brain, the synaptic architecture of the visual cortex remains in a state of flux for months after the natural onset of vision and the initial emergence of feature selectivity in visual cortical neurons. It is an attractive hypothesis that

Neural correlates of motion-induced blindness in the human brain [PDF]

open access: yes, 2010
Motion-induced blindness (MIB) is a visual phenomenon in which highly salient visual targets spontaneously disappear from visual awareness (and subsequently reappear) when superimposed on a moving background of distracters. Such fluctuations in awareness
