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:

Future applications include:

... 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.

I study the psychophysiological elements of BCIs, especially Farwell-Donchin paradigm ("P300 BCI"). One of my goals is to obtain better psychophysiological understanding of the existing BCI tasks, then use this knowledge for improving them and for creating new, more efficient BCI paradigms, allowing for easy learning and prolonged fluent use. Another goal is to understand what kinds of new opportunities are opened by providing the brain with a new "output" in a form of BCI. (The latter goal is, at the moment, not clear enough for me to make specific studies, but I've mentioned it because, nevertheless, it is also rather inspiring for me.) I also have an interest in creating BCI based games, especially in designing such games which may be helpful for training various aspects of attention.

Hello fellow BCI'ers,
Just like most of you I'm interested in BCI (surprise surprise) and everything that is associated with it. For now, my main focus is on the machine learning part. However, in the future I also plan to delve a bit deeper into possible applications for BCI.

Welcome to all members! I started my work on EEG data to continuous perediction of cursor movement in flexible way (alpha, mu, beta rhythms) during actual and imagery movements. now I continue my thesis on this approach by EEG data and ECoG data too. I focused on pattern recognition and biosignal processing methods.

Hi It's very nice to join here. I'm working on mainly BCI and some source localization issues. I've made a kind of BCI system to control computer shortly and now am trying to enhance the system as well as find good metod for BCI and signal processing.

I am particularly interested in the structure of EEG signals, the interpretation of EEG oscillations, and in signal processing methods allowing the extraction of EEG time-frequency characteristics. In other words, after dissecting EEG signals I try to search for functionally significant elements within.
I currently involved in a study of the propagation of SSVEP signals using EEG and fMRI, with applications to SSVEP-BCI.

As an epilepsy and pediatric neurosurgeon, I am interested and involved somewhat in BCI. The simplest form of BCI that neurosurgeons use is the Vagus Nerve Stimulator insertion for epilepsy, as I do here at our Neurosciences Center in Riyadh. This device indirectly communicates with the brain through the Vagus nerve to desynchronize and evolving epileptiform discharge. IT is still not very efficacious but it is what's available! it reduces severe intractable epilepsy by an average of 50 to 80 % in 50% of patients only! there are other implantables such as Dr Awan was mentioned for all types of brain malfunctions but many of what is available are still in the stage of infancy and NOT without possible complication... I am more than sure that the future has a lot to offer!

Using Computational Intelligence methodologies for BCI applications is my main interest.
Comment by Nasir Raza Awan on August 18, 2009 at 5:57pm
Interestingly, my current as well as the previous hospital that I worked in are both actively involved in research on hippocampal DBS. At the Univ of Toronto, they are studying the effects on memory and neuronogenesis after chronic electrical stimulation of hippocampus in Alzhimer's. The team in Univ of Western Ontario is studying its effects in temporal lobe epilepsy. We did one implantation about two weeks ago. Although I am not directly involved in the projects, as a neurosurgeon I can tell you that surgically it is not a difficult procedure to put an electrode in the hippocampus but whether it has any effect on memory is still a matter of active study. I am trying to get my other colleagues who are doing functional neurosurgery to join this neuro-network. One of them is doing his PhD on hippocampal DBS at Univ of T. His research has shown that chronic stimulation of hippocampus in rodent models does lead to neuronogenesis but whether these are useful neurons and whether they get incorporated into memory circuits etc still remains to be seen.

Hi Nasir Raza Awan and welcome to our group! :)
Even cochlear implantation carry its own risks.
And what about implanting hippocampal protheses into the brain? This structure is deep as can be seen on a picture. Will it be hard, from neurosurgical perspective? Is it more risky than implantations you are doing now?
Comment by Nasir Raza Awan on August 18, 2009 at 5:20pm
I am a neurosurgeon doing a fellowship in functional neurosurgery. For big part, functional neurosurgery has come to involve implantation of electrodes in the brain to alter disturbed function, although there are other procedures also that constitute functional neurosurgery.

My main interest is DBS (deep brain stimulation) for psychiatric and behavioral problems.
