Claim 0:
1. An apparatus for performing transcranial stimulation, the apparatus comprises:
a plurality of electrodes; and
a processor configured to:
generate a stimulation signal having a set of first oscillation parameters and receive a brain activity signal, wherein the generated stimulation signal and the received brain activity signal, transcranially applied and received respectively to a patient via one or more of the plurality of electrodes;
extract and deliver a portion of the stimulation signal as applied to the patient and allow the processor to monitor the stimulation signal to determine changes in voltages and/or impedance of the stimulation signal for taking into account an actual nature of the stimulation signal and generate a feedback signal thereby, wherein the feedback signal is generated based on the monitored one or more properties of the stimulation signal as applied to the patient and the set of first oscillation parameters;
generate a modified activity signal by subtracting the feedback signal, constructed in view of the monitoring of the stimulation signal from the brain activity signal, wherein the modified activity signal includes a set of second oscillation parameters, wherein the subtraction of feedback signal from the brain activity signal substantially removes an artefact from the brain activity signal that is based on stimulation signal; and
adjust the set of one or more first oscillation parameters of the stimulation signal based on the one or more second oscillation parameters of the modified activity signal, wherein adjustment of the set of one or more first oscillation parameters based on the one or more second oscillation parameters comprises iteratively optimizing the stimulation signal for a fit with the modified activity signal and triggering the application of the stimulation signal upon alignment of a phase of the stimulation signal with a phase of the modified activity signal.
