Home devices like the Muse are small and lightweight. Most are less
than $400. I am still not convinced of the signal quality of these
devices. They don’t tend to display a raw signal so it is difficult to
tell if there is noise in the signal that would negatively impact the
quality of the training. The feedback is based on changes in EEG. If the
changes are due to noise and not real EEG, then the reinforcement would
not be effective. When I have tried these devices in the past, my
experience has been that the feedback is not clearly connected to the
changes in my mental states. Other people have given me mixed reviews,
some more positive, some negative. There are a few ways that these
devices are used. One is for clients who are seeing a professional neurofeedback
provider for in office sessions. They use the home device between
office sessions. A second use if for virtual training with a
professional. The client has the device at home and the professional
coaches them virtually. The third use is for non-professionals to use at
home on their own without supervision.
2-4 channel systems like the Thought Technology Procomp-2 or
Brainmaster Atlantis 2 or 4 channel systems are mostly used for in
office sessions by professional neurofeedback providers. They are also
sometimes used for home training. They provide much more reliable
signals with raw signals displayed. These systems cost $1,600 – $3,500.
They are designed for professional use and are regulated by the FDA for
safety.
20 channel systems like the Brainmaster Discovery 20/24 do everything
that the 2-4 channel systems do plus they are also used for 19-channel
EEG recordings for brain map reports for initial and follow up
assessments. The brain maps are usually done prior to the start of neurofeedback training with clients. The cost of these systems ranges from $8,000 – $17,000. They wouldn’t be appropriate for home training due to the cost.
32+ channel systems do a form of brain mapping and neurofeedback
referred to as high density because they are using more electrode
locations. This allows for more specificity because they electrodes are
closer together so smaller areas can be measured. This is not used as
commonly in the neurofeedback field, though I expect that to change in
the years to come.
