You are right, except that the – side electrode is more commonly known as the Reference electrode instead of a Baseline electrode. The word “baseline” is more commonly reserved to describe a certain attribute of a certain brain wave at a certain site before a treatment. Most practitioners connect the Reference electrode to the earlobes (linked ears) although some connect it to the mastoid. QEEG databases use the earlobes as reference.
