Sparse coding in striate and extrastriate visual cortex
Theoretical studies of mammalian cortex argue that efficient neural codes should be sparse. However, theoretical and experimental studies have used different definitions of the term “sparse” leading to three assumptions about the nature of sparse codes. First, codes that have high lifetime sparseness require few action potentials.

In primate primary visual cortex, neurons sharing similar response properties are clustered together forming functional domains that appear as a mosaic of patches or bands, often traversing the entire cortical depth from the pia to the white matter ...

A Neural Model of How Horizontal and Interlaminar Connections of Visual Cortex Develop into Adult Circuits that Carry Out Perceptual Grouping and Learning [PDF]
A neural model suggests how horizontal and interlaminar connections in visual cortical areas Vl and V2 develop within a laminar cortical architecture and give rise to adult visual percepts.

Functional representation of vision within the mind: A visual consciousness model based in 3D default space [PDF]
The human eyes and brain, which have finite boundaries, create a ‘‘virtual’’ space within our central nervous system that interprets and perceives a space that appears boundless and infinite.

fMRI evidence that precision ophthalmic tints reduce cortical hyperactivation in migraine [PDF]
Background: Certain patterns can induce perceptual illusions/distortions and visual discomfort in most people, headaches in patients with migraine, and seizures in patients with photosensitive epilepsy.

Object repetition leads to local increases in the temporal coordination of neural responses
Experience with visual objects leads to later improvements in identification speed and accuracy (repetition priming), but generally leads to reductions in neural activity in single-cell recording studies in animals and fMRI studies in humans.
