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.
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.
Using human retinal tissue grown from stem cells, researchers shed light on how color vision develops. The study found thyroid hormones dictated whether the cells became blue, green or red photoreceptors.
