Behind the scenes, brain circuit ensures vision remains reliable
A study of mice watching movies shows our brain cells rely on a circuit of inhibitory neurons to help ensure that the same images are represented consistently.
Novel approach reverses amblyopia in animals
By temporarily suspending retinal activity in the non-amblyopic eye of animal models, neuroscientists restrengthen the visual response in the "lazy" eye, even at ages after the critical period when patch therapy fails.
Brain’s “memory center” is needed to recognize image sequences, but not single sights
The visual cortex stores and remembers individual images, but mice can’t recognize image sequences without guidance from the hippocampus.
As novel sights become familiar, different brain rhythms and neurons take over
As “visual recognition memory” emerges in the visual cortex, one circuit of inhibitory neurons supplants another, and slower neural oscillations prevail.
Eyeless roundworms sense color
C. elegans compares the ratio of wavelengths in its environment to avoid dangerous bacteria that secrete colorful toxins.
How the brain helps us remember what we’ve seen
Research finds that as one looks around, mental images bounce between right and left brain as they shift around in our visual system.
James Fujimoto wins the Visionary Prize from the Greenberg Prize to End Blindness
Historic effort to eradicate blindness marks major milestone with leading scientists recognized for pioneering work.
Neural pathway crucial to successful rapid object recognition in primates
Recurrent processing via prefrontal cortex, necessary for quick visual object processing in primates, provides a key insight for developing brain-like artificial intelligence.
Live imaging method brings structure to mapping brain function
Scientists distinguish brain regions based on what they do, but now have a new way to overlay information about how they are built.
Study sheds light on a classic visual illusion
Neuroscientists delve into how background brightness influences our perception of an object.
Study probing visual memory and amblyopia unveils many-layered mystery
Scientists pinpoint the role of a receptor in vision degradation in amblyopia.
Putting vision models to the test
Study shows that artificial neural networks can be used to drive brain activity.
How the brain distinguishes between objects
Study shows that a brain region called the inferotemporal cortex is key to differentiating bears from chairs.
The gift of light, through science and service
Professor Pawan Sinha addresses a humanitarian need — treatable blindness — and advances our understanding of visual development in the brain.
As brain extracts meaning from vision, study tracks progression of processing
Six brain regions participate in a more blended way than has been appreciated.
