Tiny Eye Movements Affect How We See Contrast
Contrast sensitivity may be a result of small eye movements people may not be aware they are making, a new study reports.... Read More...
Synaptic Logic for Connections Between Two Brain Hemispheres Discovered
Researchers have developed a new technique that helps identify the functional properties of individual synapses that link the two hemispheres of the brain.... Read More...
Surprise Discovery Reveals Second Visual System in Cerebral Cortex: Mouse Study
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. ... Read More...

Researchers have identified a white matter pathway associated with steroacuity.... Read More...
Mini Retinas Shed Light on Connection Between Eyes and Brain
Findings could help to develop new treatments to restore site when connections between the eyes and brain are damaged, researchers say.... Read More...
Surprising Network Activity in the Immature Brain
Spontaneously generated patterns of activity by local neural networks in the developing visual cortex provide the basis for long range connections that are established throughout brain activity over the course of cortical development, researchers report.... Read More...
To See What’s Right in Front of You, Your Brain May Need Some Rewiring
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.... Read More...
Teaching Computers to See Optical Illusions
Researchers have created a deep learning algorithm that can be tricked by optical illusions, just like humans. The findings shed new light on the human visual system and may help improve artificial vision.... Read More...
