Quantitative EEG and Neurotherapy Fact Sheet

The idea is to reduce slow (theta/delta – .5 – 8 Hz) wave EEG during active states and increase beta (20-30 Hz) in frontal electrodes

The brainMaster Atlantis has 4 channels to record EEG. It is $2700.

4 channels of EEG and 4 channels of AUX signals for additional biofeedback modalities. Features built in EEG driven photic stim and USB interface.

• EEG inputs sampled with 24 bits.
• Maximum EEG sampling rate (1 channel) 8192 samples/second. Presently emulating 2.5W.
• Continual impedance checking
• EEG/ Biofeedback Systems with USB Interface (no batteries, no power cord).
• Total Immersion feature (photic, vibrotactile, auditory) internal autonomous functions presently functioning with 2.5W.

An anecdote using this equipment to reduce slow-wave theta follows:

The other 3 children used one active sensor Neurofeedback of the Brainmaster 4X4 instrument.  The set up was a reference electrode on one ear (usually the left ear) and a ground electrode on the opposite ear ( obviously the right ear in this case).  The active electrode was placed at FZ in the 10-20 system of placement of electrodes.  They were to increase the amplitude of the activity at this electrode (i.e. beta of 15-18 hertz) and their feedback was to watch a pink bar go above the threshold line as much as possible.  At the same time they were to inhibit the amplitude of 4-8 hertz (theta) and of high beta ( 20-30 hertz).  They could also see the blue bar (theta) and yellow bar (high beta) stay below the threshold line.   The thresholds were set by myself after a few seconds of data collection which determined their threshold levels.  All were able to train and reported feeling calmer and more energy at the end of 5-7 minutes of training.   All of these experiments were done in front of their classmates with questions and answers being conducted as they trained.  Not the usually training conditions and yet they achieved the goal.

There is a conference that may be helpful in designing some interface that is also simple, but easy to use with iphone

This seems like a logical way in. into the analog brain state that is. Suggestions???

Ozzie could be a mind donor

The mind donors would don an EEG cap or other brain scanning device that would record their brain patterns while doing what they do best.  For example, Ozzie would be recorded while on stage at the climax of his peculiar type of ecstatic madness, and Meb Keflezighi would be recorded while running a marathon.  However, a Buddhist monk would be brain scanned while in meditation, since only monks can truly be at peace, and meditation is their particular field of mind expertise.

A mind donor monk

These mind patterns would be recorded into digital format and made available via download, pay-per-view, or as a consumer good to be purchased over-the-counter at the local bodega and traded with friends.

A mind download

Mind consumers would purchase their own consumer-level brain-scanning cap with a slot where they can plug in someone else’s mind cassette.  The consumer would  plug in a cassette with Ozzie’s or the Buddhist monk’s mind map, and they would enter into a sort of biofeedback loop with the selected mind donor.

A consumer plugged into the Buddhist monk's mind

Through the data emitted by their own brains and that of the selected mind donor, consumers train their own minds to mirror the brain patterns of Ozzie or the monk, or whichever other mind donor they choose as a reference.  Over time, consumers will learn to quickly synchronize their own brain patterns to the brain patterns of their favorite donors.

Mind feedback software

Eventually, consumers can have a library of minds to choose from.  A mind for every mood.

A collectible mind library

Following the natural evolution and democratization of technology, once the Mind Borrowing Machine proves itself technologically, there’s no reason why everyone couldn’t eventually be able to become both mind donor and mind consumer.  After all, everyone is special.

Interestingly, they provide a set of open programming APIs that allow independent developers to more easily create software that interacts with the data coming out of the device.  So, although they haven’t created any interesting applications of the device, it’s possible that someone else will.

They seem to be positioning themselves to tap into the burgeoning physical computing scene, by simplifying use of the device in projects involving the Arduino and similar microcontroller devices.

Someone from my grad school has already started working on it.
