1. A method for detecting physiological coherence in an animal subject comprising the acts of:

  • sampling a physiological measure of the animal subject;

    deriving a power spectrum distribution (PSD) from the physiological measure;

    tracking dynamically a PSD peak within a predetermined range where the PSD peak has a relative amplitude to a plurality of other peaks in the PSD;

    determining a current coherence value based on said relative amplitude and corresponding to the animal subject'"'"'s autonomic nervous system (ANS) activity;

    determining a current coherence category for the animal subject from a plurality of coherence categories which corresponds to the current coherence value; and

    providing a coherence category indication associated with the current coherence category.
