Motion Opponency in Visual Cortex [PDF]
The Journal of Neuroscience, 1999 Perceptual studies suggest that visual motion perception is mediated by opponent mechanisms that correspond to mutually suppressive populations of neurons sensitive to motions in opposite directions. We tested for a neuronal correlate of motion opponency using functional magnetic resonance imaging (fMRI) to measure brain activity in human visual cortex.

Enhanced auditory responses in visual cortex of blind rats using intrinsic optical signal imaging
Scientific ReportsFunctional maturation of the visual cortex is induced by visual experiences during critical periods. Blind animals and humans exhibit improved auditory abilities after losing their vision.

Pre-attentive segmentation in the primary visual cortex [PDF]
, 2000 The activities of neurons in primary visual cortex have been shown to be significantly influenced by stimuli outside their classical receptive fields.

The development of visual areas depends differently on visual experience. [PDF]
PLoS ONE, 2013 Visual experience plays an important role in the development of the visual cortex; however, recent functional imaging studies have shown that the functional organization is preserved in several higher-tier visual areas in congenitally blind subjects ...

Uncomfortable images produce non-sparse responses in a model of primary visual cortex [PDF]
, 2015 The processing of visual information by the nervous system requires significant metabolic resources. To minimize the energy needed, our visual system appears to be optimized to encode typical natural images as efficiently as possible.

Imaging plasticity and structure of cortical maps in cat and mouse visual cortex [PDF]
, 2001 The study reported in the first part of this thesis utilized optical imaging of intrinsic signals to visualize changes in orientation maps in cat visual cortex induced by pairing a visual stimulus with an intracortical electrical stimulation.

Quantitative MRI evaluation of glaucomatous changes in the visual pathway.
PLoS ONE, 2018 BackgroundThe aims of this study were to investigate glaucomatous morphological changes quantitatively in the visual cortex of the brain with voxel-based morphometry (VBM), a normalizing MRI technique, and to clarify the relationship between glaucomatous

Preparatory attention in visual cortex [PDF]
Annals of the New York Academy of Sciences, 2017 Top‐down attention is the mechanism that allows us to selectively process goal‐relevant aspects of a scene while ignoring irrelevant aspects. A large body of research has characterized the effects of attention on neural activity evoked by a visual stimulus. However, attention also includes a preparatory phase before stimulus onset in which the attended

Model-based analysis of pattern motion processing in mouse primary visual cortex [PDF]
, 2015 Neurons in sensory areas of neocortex exhibit responses tuned to specific features of the environment. In visual cortex, information about features such as edges or textures with particular orientations must be integrated to recognize a visual scene or ...

eLife, 2016 We hardly notice our eye blinks, yet an externally generated retinal interruption of a similar duration is perceptually salient. We examined the neural correlates of this perceptual distinction using intracranially measured ECoG signals from the human ...
