1. A method for treating a dynamical disorder, comprising: acquiring a plurality of signals corresponding to a plurality of electrodes, wherein the plurality of electrodes corresponds to a plurality of brain sites; computing a correlation between a number of signals within the plurality of signals, the number of signals corresponding to a number of brain sites within the plurality of brain sites, wherein computing the correlation comprises computing a T-index value; computing a feedback signal that is a function of the correlation and the number of signals; and applying the feedback signal to a number of transmit electrodes within the plurality of electrodes, the number of transmit electrodes corresponding to the number of brain sites.
