Size matters: MEG empirical and simulation study on source localization of the earliest visual activity in the occipital cortex
Abstract While the relationship between sensory stimulation and tasks and the size of the cortical activations is generally unknown, the visual modality offers a unique possibility...

Collicular Vision Guides Nonconscious Behavior
■ Following destruction or deafferentation of primary visual cortex (area V1, striate cortex), clinical blindness ensues, but residual visual functions may, nevertheless, persis...

LFP spectral peaks in V1 cortex: network resonance and cortico-cortical feedback
Abstract This paper is about how cortical recurrent interactions in primary visual cortex (V1) together with feedback from extrastriate cortex can account for spectral peaks in the...

Independent components of natural images under variable compression rate
A generalized ICA model allowing overcomplete bases and additive noises in the observables is applied to natural image data. It is well known that such a model produces independen...

Self-organizing maps for visual feature representation based on natural binocular stimuli
We model the stimulus-induced development of the topography of the primary visual cortex. The analysis uses a self-organizing Kohonen model based on high-dimensional coding. It all...

How do stimulus-dependent correlations between V1 neurons affect neural coding?
Nearby neurons in the visual cortex often partially synchronize their spiking activity. Despite the widespread observation of this phenomenon, its importance for visual coding and...

A computational model of monkey grating cells for oriented repetitive alternating patterns
In 1992 neurophysiologists [5] found an new type of cells in areas V1 and V2 of the monkey primary visual cortex, which they called grating cells. These cells respond vigorously to...
