Experimental software which does not sometimes work properly (no positive effect to EEG).
Software can change measurable brainwaves a bit but how it affects to brain performance is unknown.
Requires fast CPU and running times even for small effects are long (hours). Typically, you need about 100-10.000 iterations before some useful results. It means many hours of stimulation.
You need to actively concentrate on the audiovisual stimuli for hours which is tiresome. You can also only use software audio-only and listen sounds with headphones and with eyes closed.
Not for people with epilepsy. Flíckering lights and sounds.
Software increases target values (like PLI or PLV for focus) across all EEG measurement points. For the focus, you should really only increase synchronization in midfrontal brain regions in theta frequency band so overall effect to focus is speculative (if you can adjust EEG measurement points to be only in midfrontal region of the brain then increasing focus should work better).
Changes to EEG or EEG-metrics is often about 1%. 5-10% change is needed for measurable cognitive effects.
Command-line software is hard to use (there will be graphical user interface version of the software later when software functions stabilize).
