 ==================================================
 Place the gel-based electrodes firmly on the targeted scalp regions—typically the frontal (e.g., Fp1, Fp2) or occipital (e.g., O1, O2) lobes—depending on your signal of interest. Ensure that the electrodes have good skin contact and are not loose.

 To verify correct electrode placement and good signal quality, try the following actions and observe their expected EEG responses.
