Neurostimulator and method for delivering a stimulation in response to a predicted or detected neurophysiological condition

A neurostimulator, the neurostimulator implantable or wearable on a subject, the neurostimulator comprising:

• a power circuit for providing electrical power to the neurostimulator;
• a recording array having a plurality of electrodes for recording a plurality of neurophysiological signals corresponding to a plurality of sites of the subject;
• a signal processor configured to:
• determine a phase synchrony among the neurophysiological signals;
• and
• associate selected phase synchrony calculations with the prediction or detection of a neurological or neurophysiological condition;
• and
• one or more stimulators for delivering to the subject a stimulation in response to the predicted or detected condition,
• wherein the stimulation comprises generating and applying an arbitrary current-mode waveform to a subset of the stimulators and wherein the arbitrary current-mode waveform is generated by a waveform generator that provides the signal and its derivative for use in the calculation of phase synchrony.
