A couple months ago I was browsing through some old posts on the forum and I found one from September of 2006 where I talked about an application that was going to be in beta testing in “a couple months”. How’s that for an off estimate?
After two years of research and development, Mind WorkStation was finally released on Monday. We celebrated with a pizza party.
A huge amount of work went into this. This is the seventh software product we’ve released, and by far the most ambitious and complex. All through the development, release and support of the other products I’ve been taking notes about what users want to be able to do, what research needs to be done and what problems are encountered. So, in this application we had a very large to-do list. And all throughout development we were working very closely with other researchers, developers, AVS manufacturers, EEG and biofeedback vendors.
Dr. Huang’s new research played a big part in constructing the sessions that come with it. For example, we have been able to separate sessions into verbal vs non-verbal skills improvement. A session for memory has been developed, based on some very promising studies. There are also more fascinating sessions included, such as a migraine session using alternating-eye photic stimulation at 30 Hz, or a muscle contraction headache session randomly stimulating 1-3 Hz. Another even more successful migraine session uses frequencies chosen by the user based on comfort, instead of using a set protocol!
The idea of self-chosen frequencies is very interesting, especially when dealing with a large frequency range and people who have no experience with brainwave entrainment. Some choose gamma, others choose theta, others choose delta, and so on. Yet, at least with migraines, all appeared to benefit the user tremendously.
Michael Hutchison wrote that people have a subjective feeling of “connectedness” to a frequency when they are being entrained to it successfully. Perhaps this subjective feeling has a part to play in the success of self-chosen frequencies. I’ve written many times about how different everyone’s response is to brainwave entrainment. One person may respond very well to 8 Hz but not to 10. Or to 5 Hz but not to 7. EEG research has yielded some intriguing insights into why this is.
Brainwave entrainment occurs best at one’s natural dominant frequencies. In fact, the more dominant the frequency is (the higher the amplitude), the narrower the range a person can entrain to. Someone with a very high dominant 10 Hz frequency, may not be able to entrain at all to 7 Hz.
This is where EEG-Driven stimulation becomes very useful. It is a simple thing to discover a person’s dominant frequency in any frequency band, and that data can then be transferred in real-time to Mind WorkStation to be converted into audio/visual stimuli. We worked with the fine people at Thought Technology to develop a number of EEG protocols that do this. I also developed similar protocols in BioExplorer as well, so our EEG customers can do the same. The EEG-driven sessions I’ve tried so far have been nothing short of amazing.
The response to Mind WorkStation so far has been very positive. It is already being put to use developing sessions for clinics, nursing homes, ADD kids and more. I’m really looking forward to seeing what people do with it. We purposefully designed it to be as flexible as possible, so I fully expect to see it used in ways I could never have imagined. In the end, that’s the point; to make research and development in this industry easy.
Before I get back to regular blogging, I thought I would use this space to share some cool Mind WorkStation features.
In Mind WorkStation waveforms can be “morphed” into each other over time. For example, you could start with an isochronic beat, and slowly morph it into a sine wave:
Here is an animation showing what happens to the sound over time:
3D Audio Positioning
This allows you to position audio in 3D space. Take a listen to the results with a relaxation script read by Max, along with some other relaxing sounds. Listen with headphones if possible.
3D sound sample.mp3
The ambience feature randomly generates sound, reducing habituation by creating a different experience every time.
Those are three neat features I like to show off, but there is a lot more to the program. Biofeedback integration, playlists, entrainment-safe audio effects, filtering methods, new stimulation techniques, and so on. Visit the below links if you’re interested in learning more:
Better yet, download it and try it out for yourself! http://www.transparentcorp.com/products/mindws/download.php
Regular posting will resume soon. A lot has happened in the entrainment and neuroscience world in the past few months, I just haven’t had time to write about it. 🙂
