KSU BrainLab develops BCI for Google Glass, aims to improve the quality of life for locked-in people. Without doubts Google Glass has the unique potential to form the basis for a new generation of portable brain-computer interfaces. Now Neurogadget has the honour to introduce to you one of the first Google Glass Explorers who’s been using Glass in brain-computer interface research. Adriane Randolph, executive director of Kennesaw State University’s BrainLab, together with her team, has developed a working prototype that takes input from an evoked brain response to trigger the four basic interface commands for Google Glass: swipe left, swipe right, swipe down, and tap to select. While this isn’t the first time we hear about Google Glass being used for BCI purposes, there are significant differences between BrainLab’s work and other similar projects, namely This Place’s MindRDR application, which uses NeuroSky’s MindWave to let users take and share photos on Facebook, just by thinking.

EEG Signal Processing for Dummies As promised in my previous post about Event-Related Potentials, I will explain the basics and standard steps commonly used in the analysis of EEG signals. There is a lot of literature and many concepts are involved in the field of EEG signal processing, and some of them can get very technical and difficult. That is why my aim in this post is to try to give a general overview of the different concepts without getting into too much detail. Figure 1: Basic steps applied in EEG data analysis 1. Preprocessing As we can see from figure 1, the first thing we need is some raw EEG data to process. 2. The next step could be considered the most important one: feature extraction.
There are other feature extraction methods that are worth mentioning, such as EEG tomography, that allows us to compute the regions inside the brain that are active (applying the so-called inverse-problem approach). Figure 2: Example of a graph. 3. 4. Well, that's all for now. Augmented Reality. MetaMind Mind-Machine binaural beat Brainwave Lab - MeTa-MinD. MetaMindMachine is a Java open-source GPL binaural beat brainwave program, that plays binaural beats and flashes the screen in the same frequency, according to xml-style sequence files in the sequence directory, to stimulate the brain to resonate in specific EEG-brainwave-patterns.
After multiple sessions this improves the ability of the brain to go to all possible brainwave frequencies, and to switch between brainwave patterns easily and quickly. In later stages of training the user gets the ability to switch to certain brainwave-frequencies and related mental states consciously without additional technical equipment. Some studies indicate that related effects of certain brainwave frequencies, like increased immune function and release of certain neurotransmitters can result. It is also possible to optionally increase the entrainment-response effect, by using an EEG device for EEG neurofeedback training of brainwaves and transcranial electrostimulation.

Melon. InteraXon. The Brain-Computer Interface Review. Journal of Neural Engineering. Dominique M Durand et al 2014 J. Neural Eng. 11 020201 Neural engineers have made significant, if not remarkable, progress in interfacing with the nervous system in the last ten years. In particular, neuromodulation of the brain has generated significant therapeutic benefits [1–5]. EEG electrodes can be used to communicate with patients with locked-in syndrome [6]. In the central nervous system (CNS), electrode arrays placed directly over or within the cortex can record neural signals related to the intent of the subject or patient [7, 8]. A similar technology has allowed paralyzed patients to control an otherwise normal skeletal system with brain signals [9, 10]. Although there are several multichannel arrays described in the literature, the workhorse for these cortical interfaces has been the Utah array [12]. The reasons for this failure are not known but clearly involve the interface between the electrode and the neural tissue.

A brain–computer interface (BCI), sometimes called a mind-machine interface (MMI), direct neural interface (DNI), synthetic telepathy interface (STI) or brain–machine interface (BMI), is a direct communication pathway between the brain and an external device. BCIs are often directed at assisting, augmenting, or repairing human cognitive or sensory-motor functions. Research on BCIs began in the 1970s at the University of California Los Angeles (UCLA) under a grant from the National Science Foundation, followed by a contract from DARPA.[1][2] The papers published after this research also mark the first appearance of the expression brain–computer interface in scientific literature.
The field of BCI research and development has since focused primarily on neuroprosthetics applications that aim at restoring damaged hearing, sight and movement.

Arturo Vidich, Sofy Yuditskaya, and I needed a way to read brains for our Mental Block project last fall.
After looking at the options, we decided that hacking a toy EEG would be the cheapest / fastest way to get the data we wanted. Here’s how we did it. The Options A non-exhaustive list of the consumer-level options for building a brain-computer interface: Open EEG offers a wealth of hardware schematics, notes, and free software for building your own EEG system. The Nerosky MindSet is a reasonable deal as well — it’s wireless, supported, and plays nicely with the company’s free developer tools. For our purposes, though, it was still a bit spendy. Given all of this, I think the Mind Flex represents a sweet spot on the price / performance curve.
But first, the inevitable caveat: Use extreme caution when working with any kind of voltage around your brain, particularly when wall power is involved. The Hardware Here’s the basic layout of the Mind Flex hardware. The Hack Parts list: Software list: Speak Your Mind. Meta - SpaceGlasses.

MindStream – NeuroSky EEG Data Streamer. Welcome to the OpenEEG project. About the project Many people are interested in what is called neurofeedback or EEG biofeedback training, a generic mental training method which makes the trainee consciously aware of the general activity in the brain. This method shows great potential for improving many mental capabilities and exploring consciousness. Other people want to do experiments with brain-computer interfaces or just want to have a look at their brain at work. Unfortunately, commercial EEG devices are generally too expensive to become a hobbyist tool or toy. The OpenEEG project is about making plans and software for do-it-yourself EEG devices available for free (as in GPL). It is aimed toward amateurs who would like to experiment with EEG. However, if you are a pro in any of the fields of electronics, neurofeedback, software development etc., you are of course welcome to join the mailing-list and share your wisdom.
Some regulatory business Commercial and clinical EEG devices must live up to certain standards. DIY EEG (and ECG) Circuit. CAUTION: I highly suggest doing this on a laptop, because there is a danger involved if there's a spike in voltage from the wall outlet. Regardless, BE VERY CAREFUL WITH THE PROBES GOING TO THE SOUND CARD. If they accidentally touch a high voltage source (i.e. you stick them into a power outlet), you can fry your computer's sound card. First thing to do is to download Processing, available at It doesn't require any installation; just unzip the download, open the folder, and run it. Download the sketch (what programs are called in processing), and open it up. The program should be good to go as is, and while there should be enough documentation to understand what's going on in the sketch, I want to make a few notes and give a general outline of what it does here.
I encourage you to tinker with the program - change things, make your own, etc. Also, a little background on the FFT. From this, you can represent very complicated signals (any signal!)

I’ve been tinkering with tDCS for several months now – including doing lots of reading and building of prototype devices. I also have a number of friends who are giving it a try. Along the way I’ve learned a number of things that could be useful to others: 1. Read, read, read. Lots of tDCS articles and dialog are on the web and more every day. 2. Seek professional help with tDCS if at all possible. 3. 4. 5. tDCS devices built around the LM334 seem to work very well and provide very smooth adjustments to current level 6. In conjunction with the above, here is the schematic I use to build devices to tinker with. (This is my favorite design. (Almost done. (Completed except for labeling.
(Digital meter in place of analog.) (Same basic design, just digital mA meter.) And finally, here is a link to a bit of doc I’ve written for use with the home-built tDCS research device and ActivaDose II. Comments and suggestions are welcome. Like this: Like Loading... Comparing the Fisher Wallace Stimulator with tDCS : Fisher Wallace Laboratories | Fisher Wallace Stimulator. Home. DIY tDCS. Soterix Medical. Transcranial Direct Current Stimulation (tDCS) is a non-invasive procedure in which a device sends a small Direct Current (DC) across the scalp to modulate brain function.
The Soterix Medical 1x1 tDCS Low-Intensity Stimulator sends a low-level current from the positive electrode, anode, to the negative electrode, cathode. When the extremely low level current passes from the anode to the cathode, it may simultaneously increase the activity of the brain by the anode and decrease the activity of the brain near the cathode. tDCS mechanisms are considered to result from the ability of very weak DC currents to safely induce reversible changes in cortical plasticity.
The induction of lasting changes in cortical excitability can, under some conditions, reversibly modify behavior and interact with normal learning. tDCS dose can be defined as: 1) The size and position of the electrodes on the body and 2) The duration (in minutes) and intensity (in mA) of current passed across the electrodes.
