Welcome to the Brain-Machine Interfaces group!

new members Tell us about your research, why are you interested in brain-machine interfaces, share the link to your homepage or LinkedIn profile so we will know our heroes :) Write on the wall

This group is dedicated to a rapidly developing set of technologies - commonly known as brain-machine interfaces (BMI) - with a broad span of nearly-futuristic applications. Currently it allows for:

restoration of vision, hearing, movement and communication capabilities in disabled persons
repairing of brain function in such conditions as epilepsy, depression, and many others
using the power of thought to play games, send text messages and even drive cars
learning meditation, relaxation and concentration techniques

Future applications include:

direct brain-to-brain communication: seamless transfer of thoughts, emotions and experiences from one mind to another
immersive virtual reality

... and many others

How do Brain-Machine Interfaces work?

If you're interested in how current BMIs work, visit this page How Brain-computer Interfaces Work. And of course, there are lots of information on history and recent developments in BMI on Wikipedia page.

For more in-depth information, see the following list of scientific papers. I've separated them into categories. "Review papers" are general articles that describe various BMI developed by the time the article was written. Other papers describe specific approaches to BMI.

Comment by Yann Renard on July 23, 2010 at 3:15am: Hi all, I'm new to this group.
Just to introduce myself, I am software engineer at INRIA, France, leading the developments of OpenViBE (http://openvibe.inria.fr), a software for Brain Computer Interfaces and Real Time Neurosciences. I have been involved in BCIs for more than 4 years now and have been working on motor imagery, P300 spellers and SSVEP mainly. On my spare time, I also have a blog where I discuss about OpenViBE and BCIs in general (http://stickyvibe.tuxfamily.org)

Comment by Udochi Okeke on July 21, 2010 at 7:54pm: Hi all. I'm a student interested in BCI. I hope to one day get my PhD in Neuroengineering (focusing on BCI) and MD specialty in Neurosurgery. I'm very excited to have found this group. I want to learn everything I can about this field!

Comment by Alexandra Elbakyan on June 15, 2010 at 5:04am: Hello everyone!
Brice, Brendan, Nidhi - welcome to the group!

I just made a presentation at the Humanity+ 2010 summit about scientific approaches to merging human and machine minds, see here:

“Mind implants” or how to expand consciousness using new technologies

your comments and critique are welcome ;)

I created an event on this web site, but I would like to repeat it here: the Decade of the Mind project will hold its annual meeting in Singapore this year, 18-20 Oct 2010. More information and registration here: http://dom-6.org

Comment by brice rebsamen on June 15, 2010 at 3:48am: Hello everyone!
I am a postdoc at the national university of singapore. I am interested in cognitive state monitoring: mental workload, fatigue, etc.

Comment by Brendan Allison on May 5, 2010 at 1:24am: Hello - I am happy to announce the launch of our Future BNCI website. This site is meant as a central resource for BCI research, as well as work with devices based on peripheral signals. It has many resources helpful for experts and laypeople. www.future-bnci.org.

Comment by Nidhi Baweja on May 4, 2010 at 9:29pm: Hi Alexandra!
I'm just a high school student but I became really interested in Brain Computer Interface when I wrote an IT paper about it (thats how i found this site). What really interested me were the ethics involved. In regard to your previous comments on the fusion of human consciousness with artificial intelligence, the only obstacles I see are the digital divide and the possible domination of humanoids.

If we humans, have modifications done in the future, where does that leave humans? will the future dominant species of the planet be how humans are today? Of course, we would be more advanced but how would we define them as compared to today?
As you know right now, Medical oriented BCI's are very expensive and there are already deserving patients in third world countries which need BCI's but they can't afford it due to almost non-existant financial aid. this increases the gap between the have's and the have not's, thus leading to a social or economical divide globally.

Comment by Sweta Panwar on March 11, 2010 at 4:30pm: Hello Everyone,
I am just an undergrad interested in BCI, at present in my 3rd yr of integrated Masters in Converging technologies (Nano-Bio-Info-Cogno). As the course name suggests I have an interdisciplinary background and want to pursue my majors in cognitive neuroscience and merge it with IT.
I am interested in doing research work and am looking forward to get myself into a PhD after this course.

Please do let me know if you have any information about some place where I could get in as an undergrad and do some research work in the related field.

Thanks and Regards

Comment by Deema Sehli on January 6, 2010 at 6:36pm: Hello everyone,
I'm an intern who just graduated from medical school, and I'm interested in nanoneurosurgery, Neuroregeneration and neural interfacing including Nanotube-Neuron Electronic interface, Photochemical activation of Nanoparticle-film Neural Interface, Nanofibers as an aid to CNS regeneration by Neural progenitor cells, Nanofiber Brain Implants, Nanoscaffold for CNS repair and Nanoparticles for repair of SCI. I became more interested in neural interfacing system after I met Dr. John Donoghue few months ago in US and he talked about the first human implants in 2004 on four persons with paralysis and he described the progress of his trial and I was amazed by the results, He translated the thought of quadriplegic patients into an action to control a computer mouse and what made me even more impressed is that he is trying to develope a wirless interface.
