New imaging technique helps predict how vision recovers after brain tumor removal
December 10, 2014

Brad Mahon

An interdisciplinary team of University neuroscientists and neurosurgeons has used a new imaging technique to show how the human brain heals itself in just a few weeks following surgical removal of a brain tumor.

In a study featured on the cover of the current issue of the journal Science Translational Medicine, the team found that recovery of vision in patients with pituitary tumors is predicted by the integrity of myelin—the insulation that wraps around connections between neurons—in the optic nerves.

‘Red Effect’ sparks interest in female monkeys
October 17, 2014

Ben Hayden

Recent studies showed that the color red tends increase our attraction toward others, feelings of jealousy, and even reaction times. Now, new research shows that female monkeys also respond to the color red, suggesting that biology, rather than our culture, may play the fundamental role in our “red” reactions.

Seeing In The Pitch-Dark Is All In Your Head
November 1, 2013

A few years ago, cognitive scientist Duje Tadin and his colleague Randolph Blake decided to test blindfolds for an experiment they were cooking up.

They wanted an industrial-strength blindfold to make sure volunteers for their work wouldn't be able to see a thing. "We basically got the best blindfold you can get." Tadin tells Shots. "It's made of black plastic, and it should block all light."

Most People Can See Their Body's Movement In the Absence of Light

If the answer is a shadowy shape moving past, you are probably not imagining things. With the help of computerized eye trackers, a new cognitive science study finds that at least 50 percent of people can see the movement of their own hand even in the absence of all light.

"Seeing in total darkness? According to the current understanding of natural vision, that just doesn't happen," says Duje Tadin, a professor of brain and cognitive sciences at the University of Rochester who led the investigation. "But this research shows that our own movements transmit sensory signals that also can create real visual perceptions in the brain, even in the complete absence of optical input."

Enhanced Motion Detection in Autism May Point to Underlying Cause of the Disorder
May 8, 2013

Children with autism see simple movement twice as quickly as other children their age, and this hypersensitivity to motion may provide clues to a fundamental cause of the developmental disorder, according to a new study.

Such heightened sensory perception in autism may help explain why some people with the disorder are painfully sensitive to noise and bright lights. It also may be linked to some of the complex social and behavioral deficits associated with autism, says Duje Tadin, one of the lead authors on the study and an assistant professor of brain and cognitive sciences at the University of Rochester.

"We think of autism as a social disorder because children with this condition often struggle with social interactions, but what we sometimes neglect is that almost everything we know about the world comes from our senses. Abnormalities in how a person sees or hears can have a profound effect on social communication."

The Marshmallow Study Revisited
October 11, 2012

For the past four decades, the "marshmallow test" has served as a classic experimental measure of children's self-control: will a preschooler eat one of the fluffy white confections now or hold out for two later?

Now a new study demonstrates that being able to delay gratification is influenced as much by the environment as by innate ability. Children who experienced reliable interactions immediately before the marshmallow task waited on average four times longer—12 versus three minutes—than youngsters in similar but unreliable situations.

The Goldilocks Effect: Babies Learn from Experiences That Are Not Too Simple, Not Too Complex, but 'Just Right'
May 23, 2012

baby looking at computer monitor

Long before babies understand the story of Goldilocks, they have more than mastered the fairy tale heroine's method of decision-making. Infants ignore information that is too simple or too complex, focusing instead on situations that are "just right," according to a new study to be published in the open-access journal PLoS ONE on May 23.

Dubbed the "Goldilocks effect" by the University of Rochester team that discovered it, the attention pattern sheds light on how babies learn to make sense of a world full of complex sights, sounds, and movements. The findings could have broad implications for human learning at all ages and could lead to tools for earlier diagnosis of attention-related disabilities such as ADHD or autism, says Celeste Kidd, lead author on the paper and a doctoral candidate in brain and cognitive sciences at the University.

With the aid of eye-tracking devices and statistical modeling, the research is the first to provide both a theory and quantifiable measures of what keeps a baby's attention, says coauthor Richard Aslin, the William R. Kenan Professor of brain and cognitive sciences at the University.

The first-ever Walt and Bobbi Makous Prize for Excellence in Undergraduate Vision Research was presented to James Eles during the senior awards ceremony during commencement weekend. 

James Eles is a neuroscience major currently in his fifth-year in the Take-5 program where he is studying the history and psychology of warrior codes. James has had a remarkable academic career and has been on the Dean’s list every single semester. He has received a Dean’s scholarship for his studies and has been elected to Phi Beta Kappa.

Since his junior year he has worked in the department of Neurobiology and Anatomy on an independent research project in the lab of Dr. Ania Majewska. He was also awarded the prestigious Center for Visual Science undergraduate summer research fellowship to continue his work full-time during the summer. During the last few years James worked on a glutamate transporter, GLT-1, which is expressed exclusively in glial cells in the mouse cerebral cortex. He showed that GLT-1 expression can be modulated by sensory experience. This was an unexpected finding since glia are largely expected to play supportive roles to neurons and not necessarily participate in responses driven by changes in the sensory environment.

Nerve Cells Key to Making Sense of Our Senses
November 21, 2011

The human brain is bombarded with a cacophony of information from the eyes, ears, nose, mouth and skin. Now a team of scientists at the University of Rochester, Washington University in St. Louis, and Baylor College of Medicine has unraveled how the brain manages to process those complex, rapidly changing, and often conflicting sensory signals to make sense of our world. The answer lies in a relatively simple computation performed by single nerve cells, an operation that can be described mathematically as a straightforward weighted average. The key is that the neurons have to apply the correct weights to each sensory cue, and the authors reveal how this is done.

The study, published online Nov. 20 in Nature Neuroscience, represents the first direct evidence of how the brain combines multiple sources of sensory information to form as accurate a perception as possible of its environment, the researchers report.

The discovery may eventually lead to new therapies for people with Alzheimer's disease and other disorders that impair a person's sense of self-motion, says study coauthor Greg DeAngelis, professor and chair of brain and cognitive sciences at the University of Rochester. This deeper understanding of how brain circuits combine different sensory cues could also help scientists and engineers to design more sophisticated artificial nervous systems such as those used in robots, he adds.

Huxlin and Knox are exploring a new way to improve Lasik

Sometimes, even in vision research, the key to moving forward is seeing things in a new way.

That’s what happened about four years ago, when Wayne Knox ’79, ’84 (PhD), a professor of optics and physics and the director of the Institute of Optics, was presenting his work on using ultrafast lasers to change optical materials like intra-ocular lenses to a group of scientists discussing lasers, optics, and human vision.

Krystel Huxlin, an associate professor of ophthalmology at the Flaum Eye Institute, chimed in with a question: “Have you ever tried this in living materials?”

Rigorous Visual Training Teaches the Brain to See Again After Stroke
March 31, 2009

A patient undergoes visual testing.

By doing a set of vigorous visual exercises on a computer every day for several months, patients who had gone partially blind as a result of suffering a stroke were able to regain some vision, according to scientists who published their results in the April 1 issue of the Journal of Neuroscience.

Such rigorous visual retraining is not common for people who suffer blindness after a stroke. That’s in contrast to other consequences of stroke, such as speech or movement difficulties, where rehabilitation is common and successful.
