Towards zero training for brain-computer interfacing
August 13, 2008While invasive electrode recordings in humans show long-term promise, non-invasive techniques can also provide effective brain-computer interfacing (BCI) and localization of motor activity in the brain for paralyzed patients with significantly reduced risks and costs as well as novel applications for healthy users. However, two issues hamper the ease of use of BCI systems based on non-invasive recording techniques, such as electroencephalography (EEG).
First, the demands for electrode preparation for multi-channel EEG - necessary for optimal performance - are significant. Second, EEG signals are highly subject-specific and vary considerably even between recording sessions of the same user performing the same experimental paradigm.
Reporting in the online, open-access journal PLoS ONE, on August 13, a new study by Matthias Krauledat and colleagues at the Berlin Institute of Technology suggests a novel data analysis method that bypasses the need for the time-consuming calibration for long-term BCI users and may reduce the calibration time from 20?? minutes to one minute. This is achieved by a clustering approach, which extracts most representative spatial filters for each individual subject from prior recordings.
Taken together, these developments of the Berlin BCI group pave the way to make BCI technology more practical for daily use in man-machine interaction both for patients and for the healthy.

Researchers demonstrate direct brain control of humanoid robot
A classic science-fiction scene shows a person wearing a metal skullcap with electrodes sticking out to detect the person's thoughts. Another sci-fi movie standard depicts robots doing humans' bidding. Now the two are combined, and in real life: University of Washington researchers can control the movement of a humanoid robot with signals from a human brain.

Toward Brain-Computer Interfacing (Neural Information Processing) by Guido Dornhege (Editor), José del R. Millán (Editor), Thilo Hinterberger (Editor), Dennis J. McFarland (Editor), Klaus-Robert Müller (Editor), Terrence J. Sejnowski (Editor) Interest in developing an effective communication interface connecting the human brain and a computer has grown rapidly over the past decade. The brain-computer interface (BCI) would allow humans to operate computers, wheelchairs, prostheses, and other devices, using brain signals only. BCI research may someday provide a communication channel for patients with severe physical disabilities but intact cognitive functions, a working tool in computational neuroscience that contributes to a better understanding of the brain, and a novel independent interface for human-machine communication that offers new options for monitoring and control. This volume presents a timely overview of the latest BCI research, with contributions from many of the important research groups in the field. |

Introduction to Brain-Computer Interfacing Using BCI2000 (Human-Computer Interaction) by Gerwin Schalk (Author), Juergen Mellinger (Author) Brain-Computer interfaces (BCIs) use brain signals to communicate a user’s intent. Thse systems do not depend on peripheral nerves and muscles. Thus, they can be used by people with severe motor disabilities to express their wishes to the outside world just by thinking. Many laboratories have begun to develop BCI systems to provide communication and control capabilities to people with severe motor disabilities. Further progress and realization of practical applications depends on systemic evaluations and comparisons of different brain signals, recording methods, processing algorithms, output formats, and operating protocols. However, the typical BCI system is designed specifically for one particular BCI method and/or does not facilitate comprehensive BCI research programs, and is... | |

Neural Interfacing: Forging the Human-Machine Connection (Synthesis Lectures on Biomedical Engineering) by Thomas D. Coates Jr. (Author) In the past 50 years there has been an explosion of interest in the development of technologies whose end goal is to connect the human brain and/or nervous system directly to computers. Once the subject of science fiction, the technologies necessary to accomplish this goal are rapidly becoming reality. In laboratories around the globe, research is being undertaken to restore function to the physically disabled, to replace areas of the brain damaged by disease or trauma and to augment human abilities. Building neural interfaces and neuro-prosthetics relies on a diverse array of disciplines such as neuroscience, engineering, medicine and microfabrication just to name a few. This book presents a short history of neural interfacing (N.I.) research and introduces the reader to some of the... |

Neuroengineering by Daniel J. DiLorenzo (Editor), Joseph D. Bronzino (Editor) Based on a foundation of science and empirical observation, engineering research and design has brought science fiction into science fact. The convergence of neuroscience and technology is facilitating the development of therapies that not long ago would have seemed unimaginable, if not impossible. With contributions from pioneers in industry, academia, and clinical medicine, Neuroengineering provides an understanding of the history, physiology and the most promising engineering technologies. The book presents clinical applications of neuromodulation and a detailed review of the science and mechanisms of action underlying deep brain stimulation. Contributions include discussions of seizure control, clinical, surgical, and technological aspects of responsive... |
