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.

DSPdap - A DSP based Digital Audio MP3 Player & Recorder with USB pen drive funtionality, using a 16-bit fixed point Texas Instruments TMS320 C55x DSP and CompactFlash card. This is an open source and open hardware MP3 player project 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 Human Trial Suspended Animation Treatment Set to Begin at Mass General LSDBase | Measuring the Effects of Lucidity on Dreams Farm Fountain - a sculptural ecosystem you can eat 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.

5-HT2A receptor The mammalian 5-HT2A receptor is a subtype of the 5-HT2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR).[1] This is the main excitatory receptor subtype among the GPCRs for serotonin (5-HT), although 5-HT2A may also have an inhibitory effect[2] on certain areas such as the visual cortex and the orbitofrontal cortex. This receptor was first given importance as the target of serotonergic psychedelic drugs such as LSD. Later it came back to prominence because it was also found to be mediating, at least partly, the action of many antipsychotic drugs, especially the atypical ones. 5-HT2A may be a necessary receptor for the spread of the human polyoma virus called JC virus.[3] Downregulation of post-synaptic 5-HT2A receptor is an adaptive process provoked by chronic administration of SSRIs and classical antipsychotics. History[edit] Distribution[edit] Signaling cascade[edit] Effects[edit] Physiological processes mediated by the receptor include:
