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 have identified a new rule of connectivity for neurons in the neocortex, contradicting the popular belief "neurons that fire together, wire together".
Humans use the primary visual cortex to process sounds in the dark. This not only occurs in those with sight but also those who were born blind.
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.
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.
Researchers have identified cortical circuits that encode light and dark light.
