This app does not record data for later playback unfortunately. We have another app in development which is more flexible.

Blue indicates no recorded activity. Adjust the gain higher and maybe also increase the buffer length

Can the data from this device be uploaded or saved in order to send out for a QEEG. It would seem so with the 10/20 site placements. Anyone familiar with this. I am not a programmer but do use neurofeedback.

Hi, I have the same problem, I don't know how to set the gain, I make this video some days ago, and the camera is handheld, so it's difficult to relax. But I was wondering in what is happening when everything goes blue. Should the delta be set to have a higher or lower gain?

You get four maps of activity, one for each brain band. Each map has an adjustable gain (this attenuates or amplifies the signal from all channels equally) and an adjustable "buffer" which slows or speeds the rate of change of the display. It's quite an accurate representation of the spectral power in each band across the head, but the figures are relative because of the adjustable gain. It's meant to display where things are happening and how fast they change, rather than being a quantitative tool.

How accurate is the brain Map, and how do they get the specific results, as in does the brain map app just average the results across the specified frequencies, or does it adjust the amplitude gain as the frequencies increase?
You know cause the amplitude decreases as frequencies increase?
Also generally speaking MY brain map, theta area hardly shows anything BUT red, LOL is there any kind of interference that can cause that?
