ANYONE WHO STEREOTYPES video gaming as the pastime of slackers might be surprised by how Princeton professor David Tank and his research team delve into the neuroscience of navigation. Two floors below the entrance to the new Princeton Neuroscience Institute (PNI) building, behind a heavy black curtain, lies a virtual-reality game fit for a mouse. During a typical experiment, researchers project a maze, similar to what appears in 1990s-era video games, onto a small curved screen.
In 2005, Sebastian Seung suffered the academic equivalent of an existential crisis. More than a decade earlier, with a Ph.D. in theoretical physics from Harvard, Seung made a dramatic career switch into neuroscience, a gamble that seemed to be paying off. He had earned tenure from the Massachusetts Institute of Technology a year faster than the norm and was immediately named a full professor, an unusual move that reflected the sense that Seung was something of a superstar.
AS AN UNDERGRADUATE, Angelina Sylvain was fascinated to learn that devastating declines in cognition and muscle coordination could be caused by changes in a single gene — the cause of Huntington’s disease. She was intrigued by the fact that brain surgery on an epileptic patient cured him of seizures, but wiped out his ability to form short-term memories.
These remarkable discoveries first drew Sylvain to the field of neuroscience, though she never imagined that her own efforts to understand the human brain would involve training tiny worms.
PNI faculty member Yael Niv was one of four professors that received the 2013 Presidential Early Career Award for Scientists and Engineers, the highest honor bestowed by the U.S. government on science and engineering professionals in the early stages of their research careers.
When it comes to the brain, "more is better" seems like an obvious assumption. But in the case of synapses, which are the connections between brain cells, too many or too few can both disrupt brain function.
Two Princeton University projects are among the first group of studies selected by the National Institutes of Health to receive an overall $46 million in funds related to the federal BRAIN Initiative. Announced in 2013, the BRAIN (Brain Research through Advancing Innovative Neurotechnologies) Initiative aims to map the activity of all the brain's neurons.
A brain region largely known for coordinating motor control has a largely overlooked role in childhood development that could reveal information crucial to understanding the onset of autism, according to Princeton University researchers. Full Story.
Princeton faculty members William Bialek and Mala Murthy have been awarded Early Concept Grants for Exploratory Research (EAGER) by the National Science Foundation (NSF) to enable new technologies to better understand how complex behaviors emerge from the activity of brain circuits. Full Story.
People choosing between two or more equally positive outcomes experience paradoxical feelings of pleasure and anxiety, feelings associated with activity in different regions of the brain, according to research led by Amitai Shenhav, an associate research scholar at the Princeton Neuroscience Institute at Princeton University. Full Story.
On June 2nd the Neuroscience Institute celebrated the accomplishments of the graduating seniors in the Neuroscience Certificate Program. This year we had 43 students from various majors receive the certificate.
John Brinster, Class of 1943, Senior Thesis Prize
Ilana Witten, an assistant professor of Neuroscience and Psychology, was awarded a 2014 McKnight Scholars Award for her proposal entitled "Deconstructing Working Memory: Dopamine Neurons and Their Target Circuits".
Making decisions involves a gradual accumulation of facts that support one choice or another. A person choosing a college might weigh factors such as course selection, institutional reputation and the quality of future job prospects. Full Story.
A STUDY published last week found that the brains of autistic children show abnormalities that are likely to have arisen before birth, which is consistent with a large body of previous evidence. Yet most media coverage focuses on vaccines, which do not cause autism and are given after birth. How can we help people separate real risks from false rumors? Full Story.
You wouldn't hear the mating song of the male fruit fly as you reached for the infested bananas in your kitchen. Yet, the neural activity behind the insect's amorous call could help scientists understand how you made the quick decision to pull your hand back from the tiny swarm.
Cristina Domnisoru, a neuroscience graduate student in David Tank's laboratory and recipient of Princeton's prestigious Jacobus Fellowship, will be honored at an Awards Ceremony during Princeton University's Alumni Day 2014. The Porter Ogden Jacobus fellowship is the highest academic honor bestowed upon a graduate student, awarded annually to only four graduate students displaying the highest scholarly excellence in their graduate work.
