Osc raw eeg data



im trying to know what can be detected using the RAW EEG messages received via OSC from Muse Monitor iOS app. The one described as:

This is the raw EEG data for each channel on the headband as measured in microvolts.
Datatype floats
Range 0.0 - 1628.815 uV

somebody have experience working with this data and know the theory behind it and for what can be used? what exactly measure in terms of brain activity?

so far i can see theres activity pikes in TP9 and Fp2 when i blink.

any information will be highly appreciated, thank you very much…
