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). Right now, this site is mostly about the hardware; schematics, part lists, building instructions etc. Some regulatory business Commercial and clinical EEG devices must live up to certain standards. In other words, if you decide to build and use one -- the responsibility is yours.

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 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!) This program is really just a data acquisition / visualization one. Code available here.

Arduino-Brain-Library User-Built tDCS Research Device | SpeakWisdom 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. 2. 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...

EEGLAB EEGLAB provides an interactive graphic user interface (GUI) allowing users to flexibly and interactively process their high-density EEG and other dynamic brain data using independent component analysis (ICA) and/or time/frequency analysis (TFA), as well as standard averaging methods. EEGLAB also incorporates extensive tutorial and help windows, plus a command history function that eases users' transition from GUI-based data exploration to building and running batch or custom data analysis scripts. EEGLAB offers a wealth of methods for visualizing and modeling event-related brain dynamics, both at the level of individual EEGLAB 'datasets' and/or across a collection of datasets brought together in an EEGLAB 'studyset.' For experienced Matlab users, EEGLAB offers a structured programming environment for storing, accessing, measuring, manipulating and visualizing event-related EEG data.

Home BCI2000 What is BCI2000? BCI2000 is a general-purpose system for brain-computer interface (BCI) research. It can also be used for data acquisition, stimulus presentation, and brain monitoring applications. Mission The mission of the BCI2000 project is to facilitate research and applications in the areas described above. Vision Our vision is that BCI2000 will become a widely used software tool for diverse areas of real-time biosignal processing. Availability The BCI2000 system is available for free for non-profit research and educational purposes. BCI2000 development has been sponsored by a NIH (NIBIB/NINDS) Bioengineering Research Partnership grant to Jonathan Wolpaw and a NIH (NIBIB) R01 grant to Gerwin Schalk.

DIY tDCS Puzzlebox 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.
