Blind People Can’t See Color but Understand It the Same Way as Sighted People

Questioning the belief that that people born blind could never truly understand color, a team of cognitive neuroscientists demonstrated that congenitally blind and sighted individuals actually understand it quite similarly.

Retina ‘hardwired’ to predict path of moving objects

Neural circuits in the primate retina can generate the information needed to predict the path of a moving object before visual signals even leave the eye, UW Medicine researchers demonstrate in a new paper.

Scientists uncover how decisions about what we see are relayed back through the brain

Researchers at the National Institutes of Health have discovered that decisions based on visual information is broadcast widely to neurons in the visual system, including to those that are not being used to make the decision.

Brain’s ‘memory center’ needed to recognize image sequences but not single sights

A new MIT study of how a mammalian brain remembers what it sees shows that while individual images are stored in the visual cortex, the ability to recognize a sequence of sights critically depends on guidance from the hippocampus.

How neurons get past "no"

When looking at a complex landscape, the eye needs to focus in on important details without losing the big picture. Now, a new study by Salk scientists shows how inhibitory neurons play a critical role in this process.z

NIH-funded study shows children recycle brain regions when acquiring new skills

Scientists studied the brain activity of school-aged children during development and found that regions that activated upon seeing limbs (hands, legs, etc.) subsequently activated upon seeing faces or words when the children grew older.

As novel sights become familiar, different brain rhythms, neurons take over

A new study by researchers at MIT’s Picower Institute for Learning and Memory substantially advances understanding of how a mammalian brain enables “visual recognition memory.”

A new theory for what’s happening in the brain when something looks familiar

University of Pennsylvania researchers propose a new theory for how the brain understands the level of activation expected from a sensory input and corrects for it, leaving behind the signal for familiarity.

Neural Implant Monitors Multiple Brain Areas at Once, Provides New Neuroscience Insights

Researchers at UCSD have developed a neural implant that monitors the activity of different parts of the brain at the same time, from the surface to deep structures.

Sign-language exposure impacts infants as young as 5 months old

While it isn’t surprising that infants and children love to look at people’s movements and faces, recent research from Rochester Institute of Technology studies exactly where they look when they see someone using sign language.
