A serendipitous discovery and the choreographed dance of fragile X research
October 18, 2022
The choreography of development is a delicate dance. Beginning in utero, chromosomes, DNA, genes and RNA twirl, tap, and sashay their way in a precise pattern. A misstep or a missing step that changes the routine causes body and brain functions to go awry – as is the case with many intellectual and developmental disabilities (IDD). Fragile X syndrome is the most common known single-gene cause of inherited IDDs, including autism. Scientists know the misstep in this syndrome is in the gene FMR1. FMR1 is responsible for making the protein FMRP, which is necessary for typical brain development.

How do we hear one voice among many?
August 29, 2022
The ability of humans to listen and converse in noisy places like bustling city streets or crowded bars is remarkable but also mysterious. It is known, for example, that when sound waves are converted in the inner ear into electrical signals, those signals are conveyed and processed along an auditory brainstem that leads to the brain’s cortex, where auditory perception occurs.
But scientists are still trying to understand how the signal processing along this intermediate “beautiful, but complicated network of connections” helps us focus our listening, says Ross Maddox, a University of Rochester biomedical engineer and neuroscientist.

The brains of children with autism may not always ‘see’ body language
July 18, 2022
Noticing and understanding what it means when a person leans into a conversation or takes a step back and crosses their arms is a vital part of human communication. Researchers at the Del Monte Institute for Neuroscience at the University of Rochester have found that children with autism spectrum disorder may not always process body movements effectively, especially if they are distracted by something else.
Sensory processing—in a virtual Kodak Hall
June 21, 2022
A cross-disciplinary team of researchers from the University of Rochester is collaborating on a project to use virtual reality (VR) to study how humans combine and process light and sound. The first project will be a study of multisensory integration in autism, motivated by prior work showing that children with autism have atypical multisensory processing.
The project was initially conceived by Shui’er Han, a postdoctoral research associate, and Victoire Alleluia Shenge ’19, ’20 (T5), a lab manager, in the lab of Duje Tadin, a professor of brain and cognitive sciences.

Walking gives the brain a ‘step-up’ in function for some
June 17, 2022
It has long been thought that when walking is combined with a task – both suffer. Researchers at the Del Monte Institute for Neuroscience at the University of Rochester found that this is not always the case. Some young and healthy people improve performance on cognitive tasks while walking by changing the use of neural resources. However, this does not necessarily mean you should work on a big assignment while walking off that cake from the night before.
How the brain interprets motion while in motion
June 13, 2022
Imagine you’re sitting on a train. You look out the window and see another train on an adjacent track that appears to be moving. But, has your train stopped while the other train is moving, or are you moving while the other train is stopped?
The same sensory experience—viewing a train—can yield two very different perceptions, leading you to feel either a sensation of yourself in motion or a sensation of being stationary while an object moves around you.
Human brains are constantly faced with such ambiguous sensory inputs. In order to resolve the ambiguity and correctly perceive the world, our brains employ a process known as causal inference.
Causal inference is a key to learning, reasoning, and decision making, but researchers currently know little about the neurons involved in the process.
In a new paper published in the journal eLife, researchers at the University of Rochester, including Greg DeAngelis, the George Eastman Professor of Brain and Cognitive Sciences, and his colleagues at Sungkyunkwan University and New York University, describe a novel neural mechanism involved in causal inference that helps the brain detect object motion during self-motion.
Knowing How the Brain Reacts to Smells May Help Fight Disease
May 11, 2022
You know that complicated equations can predict what story pops up in your news feed or which TikTok video you’ll watch next. But you might not know that math can help us understand what happens in the brain when we smell something.
Researchers at the Del Monte Institute for Neuroscience at the University of Rochester are building complex mathematical models that do just that – and if they continue to make progress, their work may aid in the fight against diseases of the nervous system, like Alzheimer’s and Parkinson’s.
Diverse minds and determined hearts make change: Forging equitability in Neuroscience
April 25, 2022
A group, mostly consisting of neuroscientists, meets bi-weekly outside the lab with a simple but powerful common purpose – to fundamentally change the bench.
"This experience has been eye-opening,” said Manuel Gomez-Ramirez, Ph.D., assistant professor of Brain and Cognitive Sciences at the University of Rochester and chair of the Del Monte Institute for Neuroscience Diversity Commission. “It is such a diverse group in every sense – cultural, gender, experience in both academics and nonacademics – we are all able to have input and listen to each other while considering different perspectives and focusing on one problem together."

The art of smell: Research suggests the brain processes smell both like a painting and a symphony
April 4, 2022
What happens when we smell a rose? How does our brain process the essence of its fragrance? Is it like a painting – a snapshot of the flickering activity of cells – captured in a moment in time? Or like a symphony, an evolving ensemble of different cells working together to capture the scent? New research suggests that our brain does both.
"These findings reveal a core principle of the nervous system, flexibility in the kinds of calculations the brain makes to represent aspects of the sensory world," said Krishnan Padmanabhan, Ph.D., an associate professor of Neuroscience and senior author of the study recently published in Cell Reports. "Our work provides scientists with new tools to quantify and interpret the patterns of activity of the brain."

A key to restoring sight may be held in a drug that treats alcoholism
March 18, 2022
Researchers may have found a way to revive some vision loss caused by age-related macular degeneration – the leading cause of blindness – and the inherited disease retinitis pigmentosa (RP), a rare genetic disorder that causes the breakdown and loss of cells in the retina. The drug disulfiram – marketed under the brand name Antabuse – used to treat alcoholism, may hold the key to restoring this vision loss.
Researchers restore brain immune system function after prenatal exposure to environmental toxin
February 11, 2022
From Medical Xpress
New research shows that exposure to the industrial byproduct TCDD in utero could cause the brain's immune system to go array later in life, damaging important brain circuits, and potentially giving rise to neurodevelopmental disorders, such as autism and ADHD. TCDD is primarily released into the environment by vehicle exhaust and burning wood and low levels of the toxin are found in air, soil, and food. The most common way people are exposed is through meat, dairy, and fish.

Researchers provide insight into how the brain multitasks while walking
January 24, 2022
New research turns the old idiom about not being able to walk and chew gum on its head. Scientists with the Del Monte Institute for Neuroscience at the University of Rochester have shown that the healthy brain is able to multitask while walking without sacrificing how either activity is accomplished.
Student Spotlight: Bryan Redmond
January 24, 2022
Bryan Redmond is a second year in the Neuroscience Graduate Program, and fourth year in the Medical Scientist Training Program at the University of Rochester School of Medicine and Dentistry. Redmond graduated from Xavier University of Louisiana with a B.S. in psychology.
Redmond’s research interest lies in the visual deficits experienced following optical lobe stroke. He is currently working in the lab of Krystel Huxlin, Ph.D., investigating whether neurons in undamaged areas of the visual circuit can be stimulated to restore vision following stroke. “There are no gold standard therapies for helping these patients recover their vision,” Redmond said. “If you have a motor stroke, you go to rehab, and keep training a muscle until you regain function. Patients with visual stroke are taught compensatory eye movements to make up for the blind field segment, or they are prescribed glasses with special lenses. These options teach patients to cope with their deficiency. We hope to develop a way to help them recover.”
How we recognize one voice in a noisy crowd
January 11, 2022
From The Optimist Daily
Whether we’re at a busy restaurant, birthday party, or on public transport, sometimes our brain needs to focus on a single speaker amongst a multitude of background noise. A group of scientists from the University of Rochester Medical Center, wanted to see exactly how our incredible organ processes these stimuli.
The research team, led by Edmund Lalor, Ph.D., looked at exactly how our brains focus on the information from one speaker, whilst blocking out the background. Willing participants were asked to listen to two stories being told at once, and hold their attention on only one. EEG brainwave recordings were taken to try and unlock the neuronal activity occurring.
Changes in the brain hinder addiction recovery in people who are HIV-positive
December 20, 2021
Researchers with the Del Monte Institute for Neuroscience at the University of Rochester are studying how the brain puts the 'brakes' on behavior. That may be different in individuals recovering from cocaine addiction and who are also HIV-positive.
“Scientists have long known that drug abuse can cause damage to the brain. We also know HIV infection can cause brain changes,” said John Foxe, Ph.D., director of the Del Monte Institute for Neurosciences and senior author of the study published in Neuropharmacology. “Since drug use is common in individuals with HIV, an important question is how brain deficits associated with both conditions might add up.”
Why some misremembering might show your memory is functioning properly
December 18, 2021
From The Washington Post
When asked the other day about a bakery near my home, I responded that I’d recently eaten its mouthwatering chocolate chip cookies. My wife corrected me, noting that the cookies I ate were actually oatmeal raisin.
Why did I make this memory error? Is this an early sign of impending dementia? Should I call my doctor?
Or is forgetting the details of a dessert a good thing, given that everyday life is filled with an enormous number of details, too many for a finite human brain to remember accurately?
URMC researchers reveal how the brain understands one voice in a noisy crowd
December 15, 2021
In a crowded room where many people are talking, such as a family birthday party or busy restaurant, our brains have the ability to focus our attention on a single speaker. Understanding this scenario and how the brain processes stimuli like speech, language, and music has been the research focus of Edmund Lalor, Ph.D., associate professor of Neuroscience and Biomedical Engineering at the University of Rochester Medical Center.
New Eye Drops Offer an Alternative to Reading Glasses
December 14, 2021
From The New York Times
An eye drop that improves close-range vision could make misplaced reading glasses less of an inconvenience for many of the 128 million Americans who suffer from age-related deficits in near vision. Vuity, which became available by prescription on Thursday, is a once-a-day treatment that can help users see up close without affecting their long-range vision.
“For anybody who doesn’t want to fiddle with reading glasses, this might be a really helpful alternative,” said Dr. Scott M. MacRae, an ophthalmologist at the University of Rochester’s Center for Visual Science. Dr. MacRae was not involved in the clinical trials for the drug, which was approved by the U.S. Food and Drug Administration in late October.
A cure for blindness? A next-generation solar concentrator?
December 7, 2021
The most efficient photovoltaic cells used for solar power cost up to $50,000 per square meter. What if these cells could be replaced with a plastic solar concentrator less than 3 mm thick that concentrates sunlight 500 times at only $100 per square meter?
Diseases that cause blindness destroy the rods and cones in the retina. Ganglion cells rely on rods and cones to detect light as it comes into the eye. Could blindness be cured if ganglion cells could be coaxed by genetically engineered viruses to take on this function?
These tantalizing prospects are being pursued by two celebrated University of Rochester scientists whose work has already proven transformative, resulting in their election as 2021 fellows of the National Academy of Inventors.
Brief period of ‘blindness’ is essential for vision
November 19, 2021
We need to constantly shift our gaze to allow the foveola, a small region at the center of the retina, to get a full view of the world, similar to rotating a telescope to get a full view of a scene. Unlike when we might rotate a telescope, however, our eyes make most of these gaze shifts, especially the smallest ones, on their own, often beneath our awareness. By studying how a type of fixational eye movement called a microsaccade affects the foveola, Rochester researchers provide important foundational information that can lead to improved treatments and therapies for vision impairments.

Fixational eye movements are tiny movements of the eye—so small we humans aren’t even aware of them. Yet they play a large role in our ability to see letters, numbers, and objects at a distance.
In a new paper published in Proceedings of the National Academy of Sciences, researchers at the University of Rochester, including Michele Rucci, a professor of brain and cognitive sciences, and Janis Intoy, a postdoctoral research associate in Rucci’s lab, further cement the evidence for the important role of these tiny movements. By studying how a type of fixational eye movement called a microsaccade affects the foveola, a small region at the center of the retina, the researchers provide important foundational information that can lead to improved treatments and therapies for vision impairments.
