Hi, i'm confused by this reading, my delta seems extremely high but i'm pretty sure that i am awake :) am i reading this wrong (as in higher dB is less "activation")?

High Delta when awake is a result of poor sensor contact, or EMG (muscle movement) interference.

Switch over to the RAW EEG view; This one - https://mind-monitor.com/img/mm-screen-3.jpg

What you want to get here are thin crisp lines, with large spikes when you blink or move your eyes quickly.

In the example picture here you can see how TP9 is more "fuzzy" than the rest, this means the connection is not so good. It's ok, but it could be better! ;-)

Interaxon advertise the Muse as having dry sensors, but in reality they still rely on a thin film of sweat to conduct the electric signal from your skin. To help with the connection I would recommend that you dip your finger in some clean water, then rub the sensors before putting it on. After about a minute the water will have evaporated, and the sweat connection will be in place. It also helps to gently scrub your skin clean before putting on the Muse, to get the best connection. Dry skin flakes, makeup/foundation or dirt will block the signal. Also tie back your hair to make sure the ear connections are not blocked.
