 Step 3: Attaching Gel Electrodes on Targeted Areas
 ==================================================
+
 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.
