ITHACA, N.Y. - As neuroscientists examine challenging questions about the complexities of the central nervous system, new tools to be developed at Cornell University will provide them with an unprecedented glimpse into the inner workings of the brain thanks to a five-year, $9 million grant from the National Science Foundation.
The grant will establish the Cornell Neurotechnology NeuroNex Hub, which will focus on researching, developing and disseminating new optical imaging tools for noninvasive recording of neural activity in animals. It will also establish the Laboratory for Innovative Neurotechnology at Cornell, where engineers and biologists will collaborate on developing and testing the tools.
The hub aims to overcome three barriers faced by neuroscientists:
Within five years, the hub aims to integrate the three tools to demonstrate the deepest, high-resolution, large-scale neural activity recording ever achieved.
"It is well recognized that neurotechnology development is essential to push the envelope of neuroscience. At the Cornell NeuroNex Hub, we will create, optimize and then disseminate the new tools that will enable biologists to attack some of the impossible problems in neuroscience," said Chris Xu, professor of applied and engineering physics, and principal investigator for the hub.
Using the technology, biologists hope to explore unanswered questions, such as how animals consciously switch from autonomous locomotion to deliberate limb placement.
"Behaviors emerge from interactions of neurons widely distributed in brains, but we do not yet have the tools we need to simultaneously monitor single-cell activity widely in the brains of diverse species," said Joseph Fetcho, professor of neurobiology and behavior, and a senior investigator for the hub.
The hub is part of the larger Cornell Neurotech program launched with a multimillion-dollar gift from the Mong Family Foundation in 2015 with the same goal of encouraging cross-disciplinary research to develop new tools for neuroscience. The hub will also educate the next generation of scientists by involving graduate and undergraduate students who will learn to collaborate across such disciplines as biology, computer science, engineering, medicine and physics.
"In many ways, Cornell Neurotech has been growing at a rate faster than we could have anticipated," said Gretchen Ritter '83, the Harold Tanner Dean of Arts and Sciences. "This trajectory is prompted both by the leading-edge imaging work of its researchers, as well as the attention that Cornell's investment in neurotechnology has been generating more broadly."
Added Lance Collins, the Joseph Silbert Dean of Engineering: "It's been exciting to see this Neurotech initiative blossom here at Cornell, which really is an ideal place to make great discoveries in neurotechnology and neuroscience. We not only have the collaborative environment, but we have a proud history of pioneering new technologies."
A large number of academic and industry partners across the nation have already signed on to participate in the hub, which will be led by Xu, Fetcho, Chris Schaffer, associate professor of biomedical engineering, Nilay Yapici, assistant professor of neurobiology and behavior, and Mert Sabuncu, assistant professor of electrical and computer engineering and of biomedical engineering.
