I have recently decided to try and enhance my meditation with neuro-feedback by using an EEG headset with meditation software programs.
From what I have read regarding meditation and EEGs:
1. Focused attention on an object of meditation such as one's breath, an idea, image or emotion corresponds to Gamma waves of about 30-50 Hz and possibly Beta 20-30 Hz.
2. Vipassana & Zazen - Open monitoring of ongoing experience without judging, reacting or attachment corresponds to Frontal Theta waves of about 4 or 5 to 8 Hz.
3. Automatic self-transcending (transcendental) corresponds to Frontal Alpha waves of about 8 to 10 or 12 Hz.
I've just started using a MindPlay app from NeuroSky and am considering downloading Zen-Fire Meditation Toys freeware from SourceForge (which includes a Theta driver among the toys), but am still cautiously investigating that one. Sekati looks fantastic, but I think it might require a headset with headphones. I will probably get the "Chanter" by Jeff Winder featured on the NeuroSky online store, but wish I knew more about exactly how it evaluates the particular brain waves as representing "enhanced" meditation.
I'm looking for helpful advice from anyone familiar with neuro-feedback brainwave training, who might also hopefully recommend good meditation apps which are compatible with a MindWave headset. I particularly would like to know if focusing on "Theta" waves does indeed enhance Vipassana.
