Infra-low Frequency (ILF) neurofeedback refers to training the very slowest brainwaves (less than .5Hz).
These basic cortical rhythms of the brain underlie our higher brain functions. The slower frequencies are linked to the faster ones through harmonics¹; this means that by training the lower frequencies you can effect the higher ones, and vica-versa².
The long wavelength of Infra-Low brainwaves make them difficult to detect and accurately measure, so little research has been done. They appear to play a role in brain timing and network function³.
You can think of ILF neurofeedback as shifting the ocean floor; a small change in the seabed can make a big impact on the surface.
There are two approaches to ILF training; ILF neurofeedback, and pEMF.
ILF NEUROFEEDBACK
ILF neurofeedback began in 2006, and we began using it in 2008. It is in its infancy, and still has a few limitations to overcome. The main difficulty is the feedback itself; a frequency of .1HZ means one wave every 10 seconds. The slower the wave, the lower the resolution, and the more sluggish and inaccurate the feedback is.
NEUROFIELD PEMF
For training at these low frequencies, we use the Neurofield (pEMF) rather than neurofeedback. It allows us to get the brain to ‘chime along’ to a steady slow rhythm, restoring regulation through gentile stimulation rather than feedback. We have found it gives more stable, reliable, and faster results than the EEG approach.
Infra-low training is only appropriate in some cases, but if called for it can be very effective.
