Researchers report single neurons in the primary visual cortex can reliably detect straight lines, even though the makeup of the cell is constantly changing.
Researchers provide new evidence of brain plasticity. A new study reveals visual cortex neurons sprout new axons and shed some old ones as animals improve at perceptual learning tasks.
Researchers have identified a new rule of connectivity for neurons in the neocortex, contradicting the popular belief "neurons that fire together, wire together".
A new study challenges 75 year old dogma of mammalian vision. Researchers have shows the post rhinal cortex obtains visual data from the superior colliculus and is not dependent upon information from primary visual cortex.
Researchers report life experiences may be transgenerationally inherited through a combination of epigenetics and parental behavior.
Researchers find neural activation patterns were predictive of the contents of voluntary visual imagery as far as 11 seconds before the choice of what to imagine. These results suggest that the contents of future visual imagery can be biased by current or prior neural representations.
Retinal ganglion cell survival following a stroke depends on whether the pathway to the primary visual area remains active. Cells connected to inactive areas of the visual cortex suffer atrophy and degenerate, leading to permanent visual impairment.

··5 min readMEG neuroimaging implicates the occipital place area (OPA) in our ability to rapidly sense our surroundings. The findings may advance improving machine learning and robotics technology aimed at mimicking visual processes in the human brain.
Researchers say measuring signals from a single neuron may be as good as capturing information from many neurons at once.
Visual neurons selectively respond to color and shape along a continuum. While some neurons are only activated by either a specific color or shape, others are responsive to color and shape simultaneously. The findings contradict previous beliefs about how visual processing works.
When learning a new task, brain activities alter over time as mice transition to an expert from a novice. The changes are reflected in neural networks and neural activity. As the animal's knowledge grows, neural networks become more focused.
Study provides new evidence supporting the theory that perceptual limitations are caused by a correlated noise in neural activity.
