Noradrenaline is essential for astrocytes to respond to local stimulation.
Using optogenetics, researchers stimulated neurons in the visual cortex of mice to induce illusory images in the animals' minds.

Adults who played Pokemon video games as children had preferential activation in the visual system for Pokemon character, researchers report. The finding shed light on the development of the visual system and categorization in the brain.
CT1 cells connect around 1400 areas in the fly brain. Each cell area works like a separate neuron, allowing CT1 to access information from the fly's eye and support local motion detection.

In uveitis, microglia facilitates the entry of inflammatory immune cells into the retina, enabling the host immune responses to attack cells not normally recognized by the immune system.
Researchers report signals from the retina are subjected to selective processing at the earliest neural way-station in the functional pathway connecting the retina to the visual cortex.
A new study reports those who smoke 20 or more cigarettes a day have a reduced ability to discriminate contrast and colors compared to non smokers.
Contrast sensitivity may be a result of small eye movements people may not be aware they are making, a new study reports.
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.
Differences in activity between the left and right superior colliculi help researchers predict whether an animal was seeing an event.
