Unraveling the Complexity of the Brain

The brain is a complex system consisting of microscopic and macroscopic networks that give rise to its function. Efforts to understand the brain require simultaneous measurements at multiple spatiotemporal scales. Over the years, technology has been established to record high-dimensional electrical activity from a network of brain cells at small (single neurons) and large (local field potentials and electrocorticography [ECoG]) scales. Recent advances in optogenetic techniques have further enabled the possibility of imaging and controlling a large number of neurons.

The ability to collect high-dimensional neural activity introduces the great challenge of analyzing and modeling this activity to understand the brain’s function and dysfunction, to devise novel treatments for various neurological disorders, and to enhance brain function. Advanced mathematical techniques are being developed spanning the fields of machine learning, signal processing, control, and information theory. Novel photonic and genetic techniques are being explored for increasingly precise optogenetic imaging and control. Finally, development of the next generation of neurotechnologies requires the design of low-power biocompatible electronic implants that can simultaneously record and stimulate the brain, and wirelessly transmit the recorded data to the outside world.

This session explored these challenges and the advances that engineers have made to tackle them. It began with a talk by Ellis Meng (University of Southern California) on technologies to interface with the brain for recording and modulation. She was followed by Jose Carmena (University of California, Berkeley), who discussed efforts to understand the neural basis of skill learning using brain-machine interfaces. The third speaker, Konrad Kording (University of Pennsylvania), described new models for neuroscience. The session concluded

with a talk by Azita Emami (California Institute of Technology) on efficient feature extraction and classification methods in neural interfaces.

Together these efforts will help pave the way to understand the brain, treat its disorders, and enhance its functions.

This volume presents papers on the topics covered at the National Academy of Engineering's 2017 US Frontiers of Engineering Symposium. Every year the symposium brings together 100 outstanding young leaders in engineering to share their cutting-edge research and innovations in selected areas. The 2017 symposium was held September 25-27 at the United Technologies Research Center in East Hartford, Connecticut. The intent of this book is to convey the excitement of this unique meeting and to highlight innovative developments in engineering research and technical work.
