Mind Monitor

Hello everyone,
I recently completed a 15-minute meditation session and observed that my Delta waves are consistently high (see attached graph). Does anyone have any tips or advice on this? I'm keen to understand more about what this means and how to optimize my meditation practice. Thanks in advance!

High Delta while awake is a result of poor sensor contact. The EMG (muscle movement) interference is picked up as Delta as this is the lowest frequency wave. To check for good sensor contacct, switch to the RAW EEG view and try to get the voltage variance under 50uV with thin crisp lines. You should only see spikes when you blink.
