Closely analogous to coupled-oscill<strong>at</strong>or phenomena seen<br />
elsewhere in physical science and engineering.<br />
Rel<strong>at</strong>ive values of oscill<strong>at</strong>or amplitudes and couplings<br />
reflect st<strong>at</strong>e of the system, so...<br />
Maybe there are changes with depth of anæsthesia?<br />
