Washington, D.C. – Michael Yartsev is the 2013 Grand Prize winner in the annual international competition for The Eppendorf & Science Prize for Neurobiology. Yartsev is being recognized for his outstanding research contributions into the neural coding mechanisms underlying three-dimensional spatial memory and navigation in the mammalian brain.

"All animals on our planet, either on the ground, the ocean depths, or in the sky, must have knowledge of their whereabouts to survive," said Yartsev, a research associate and C. V. Starr Fellow at the Princeton Neuroscience Institute at Princeton University. "How the brain solves the problem of knowing where we are in space is a central question in neuroscience."

Yartsev was able to answer a longstanding question about the mechanisms the brain uses to navigate "from a different angle by studying an unusual and novel animal model—the bat," said Melissa McCartney, Science associate editor and member of the Prize jury committee. (For many years, studies designed to test spatial memory in mammals have been done in rodents.) "He was able to further our understanding of how spatial memory is represented in the mammalian brain," said Peter Stern, Science's senior editor, who chaired the Prize jury.

Mammalian navigation has been linked to the hippocampus, and in particular to hippocampal neurons called "place cells," which fire when an animal is in a specific location to help that animal orient. Until now, however, it has been unclear whether navigation processes identified in ground dwellers -- which typically navigate along 2D environments -- are the same in creatures that fly -- which navigate in 3D.

In his award-winning essay, "Space Bats: Multi-dimensional spatial representation in the bat hippocampal formation," which will be published in Science this Friday, Yartsev highlights his discovery that place cells do indeed help bats navigate 3D space. Notably, the neural processes he and colleagues found bats to use to navigate 3D space were different from those previously identified in rats.

"Our study in bats allowed for causal examination of a major class of models that were based solely on data from rats," he wrote, adding that "the use of novel animal models in neuroscience can complement existing knowledge and provide insights into the inner workings of the brain."

While conducting his doctoral research at the Weizmann Institute of Science in Israel, Yartsev worked in the laboratory of Nachum Ulanovsky and recorded the activity of single neurons in the hippocampus of freely behaving and flying bats. "The use of a novel animal model along with the technological development to monitor the activity of single neurons during flight, allowed us to conduct both causal examinations of leading hypotheses in the field as well as to provide novel insights into the neural codes underlying the representation of three-dimensional space in the brain," Yartsev explained. "In the future, I plan to use bat's unique behavioral repertoire and sensory system, along with the technology to monitor the activity of single neurons during flight to also study the computations taking place in the brain during decision-making processes."

The Eppendorf and Science Prize in Neurobiology recognizes outstanding international neurobiological research based on current methods and advances in the field of molecular and cell biology by a young early-career scientist, as described in a 1,000-word essay based on research performed within the last three years. The grand prize winner receives $25,000 from Eppendorf, and the winner's essay will be published in the 1 November 2013 issue of the journal Science.

"I am truly blown away," expressed Yartsev, the 12th winner of the prize, about his work's recognition. "Given the caliber of past winners and runner-ups, I feel extremely honored and grateful for being chosen to receive this prize."

The winner and the finalists will be recognized at the annual meeting of the Society for Neuroscience on Sunday, 10 November 2013, in San Diego, California.

2013 Grand Prize Winner

Michael M. Yartsev, for his essay "Space Bats: Multi-dimensional spatial representation in the bat hippocampal formation." Yartsev received his PhD from the Weizmann Institute of Science. There, he recorded the activity of single neurons from the hippocampal formation of freely behaving and flying bats to study the underlying neural mechanisms of spatial memory and navigation in the mammalian brain. Since 2012, Yartsev is a C. V. Starr Fellow at the Princeton Neuroscience Institute at Princeton University where he is conducting postdoctoral work in the laboratory of Prof. Carlos Brody studying the neural basis of decision-making.

Finalists

Sophie J.C. Caron, for her essay "Brains don't play dice—or do they?" Caron is currently a postdoctoral fellow in the Department of Neuroscience at Columbia University. Sophie grew up in St-Blaise-sur-Richelieu in Canada and earned a B.Sc. in Biochemistry at the Université de Montréal. She moved to New York City to study the developmental mechanisms behind the diversification of sensory neurons in the laboratory of Alexander Schier at New York University and, later, Harvard University. After completing her PhD, Caron joined the laboratory of Richard Axel at Columbia University, where she studies how the information gathered through the senses is represented in higher brain centers, in particular those involved in memory. http://scim.ag/Caron.

Daniel Bendor, for his essay "Play it again brain." Bendor is a Lecturer in the Department of Cognitive, Perceptual, and Brain Sciences and the Institute of Behavioral Neuroscience at University College London. Bendor received his PhD from Johns Hopkins University under the mentorship of Xiaoqin Wang, studying temporal processing in auditory cortex and the neural correlate of pitch and flutter perception. For his postdoctoral research, he investigated the role of the hippocampus in memory encoding and consolidation, while working with Matthew Wilson at the Massachusetts Institute of Technology. He recently started his own lab at University College London, where his research focuses on how neural ensembles encode perceptual and memory-related information. http://scim.ag/Bender.
