EEG and HRV

The idea here is that we can use simple devices to provide neurofeedback and interface with smarphones. Heart Rate Variability and EEG are physio biomarkers that can be modulated by self-regulation to adaptive levels provided visual feedback.

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

    Hmm. $2,700 is a bit steep for an iphone accessory. Is there a way to make EEG cheaper? Do we need EEG at all if we’re focused on HRV?

  2. I think the Neuro Sky has to be worth pursuing. I have been working on an EMDR machine http://www.rewire-my-brain.com/emdr/ which feels like it’s doing good things, but it has (only just) occurred to me that it would be interesting to use the Neuro Sky EEG and the Heart Math emWave2 PC software to actually quantify the results.

    Right now I’m looking for anything that can help to rewire my brain with respect to (over) eating!
