What do we know about 40 Hz activity and the function it serves?

Abstract

This section is intended to be clinically focused. Therefore, contributions are often more informal and do not always include references. Our clinical work is guided by science whenever possible, but limitations in knowledge require practitioners to be guided often by clinical experience, no matter what their specialty. In other words, clinical work involves art as well as science. Thus, contributions to this section will refer both to science and to “clinical wisdom.” Readers may send questions to: D.
