Does shape discrimination by the mouth activate the parietal and occipital lobes? - near-infrared spectroscopy study. [PDF]

open access: yesPLoS ONE, 2014
A cross-modal association between somatosensory tactile sensation and parietal and occipital activities during Braille reading was initially discovered in tests with blind subjects, with sighted and blindfolded healthy subjects used as controls. However,

Toward a Theory of the Striate Cortex [PDF]

open access: yesNeural Computation, 1994
We explore the hypothesis that linear cortical neurons are concerned with building a particular type of representation of the visual world—one that not only preserves the information and the efficiency achieved by the retina, but in addition preserves spatial relationships in the input—both in the plane of vision and in the depth dimension.

Investigating unique environmental contributions to the neural representation of written words: a monozygotic twin study. [PDF]

open access: yesPLoS ONE, 2012
The visual word form area (VWFA) is a region of left inferior occipitotemporal cortex that is critically involved in visual word recognition. Previous studies have investigated whether and how experience shapes the functional characteristics of VWFA by ...

Coordinated optimization of visual cortical maps (II) Numerical studies [PDF]

open access: yes, 2012
It is an attractive hypothesis that the spatial structure of visual cortical architecture can be explained by the coordinated optimization of multiple visual cortical maps representing orientation preference (OP), ocular dominance (OD), spatial frequency,

Towards a 'canonical' agranular cortical microcircuit

open access: yesFrontiers in Neuroanatomy, 2015
Based on regularities in the intrinsic microcircuitry of cortical areas, variants of a 'canonical' cortical microcircuit have been proposed and widely adopted, particularly in computational neuroscience and neuroinformatics.

Audiovisual Blindsight: Audiovisual learning in the absence of primary visual cortex

open access: yesFrontiers in Human Neuroscience, 2016
Learning audiovisual associations is mediated by the primary cortical areas; however, recent animal studies suggest that such learning can take place even in the absence of the primary visual cortex.

Abnormal intra-network architecture in extra-striate cortices in amblyopia: a resting state fMRI study

open access: yesEye and Vision, 2019
Background Amblyopia (lazy eye) is one of the most common causes of monocular visual impairment. Intensive investigation has shown that amblyopes suffer from a range of deficits not only in the primary visual cortex but also the extra-striate visual ...

Gestalts at threshold could reveal Gestalts as predictions

open access: yesScientific Reports, 2021
We review and revisit the predictive processing inspired “Gestalts as predictions” hypothesis. The study of Gestalt phenomena at and below threshold can help clarify the role of higher-order object selective areas and feedback connections in mid-level ...

Paired Feed-Forward Excitation With Delayed Inhibition Allows High Frequency Computations Across Brain Regions

open access: yesFrontiers in Neural Circuits, 2022
The transmission of high frequency temporal information across brain regions is critical to perception, but the mechanisms underlying such transmission remain unclear.

Functional Organization of Visual Cortex in the Owl Monkey [PDF]

open access: yes, 2004
In this study, we compared the organization of orientation preference in visual areas V1, V2, and V3. Within these visual areas, we also quantified the relationship between orientation preference and cytochrome oxidase (CO) staining patterns. V1 maps of
