1. A method for detecting a brain response state of a subject, wherein said method comprising:

  • repeatedly presenting said subject with a sound stimulus for evoking a brain response;

    detecting an evoked brain response signal related to each of said sound stimulus, wherein said evoked brain response signal is an electrophysiological signal and said evoked brain response signal comprises at least one peak related to an evoked response of at least one neuron;

    determining a time window, said time window has a time width covering at least partly one of said at least one peak in said evoked brain response signal;

    calculating an average evoked response signal based on said evoked brain response signals over said time window;

    or calculating an average value based on one of said evoked brain response signal over said time window;

    comparing said evoked brain response signals over said time window with said average evoked response signal;

    or comparing subparts of said evoked brain response signal over said time window with said average value; and

    determining a variance and/or volatility of at Least one neuron'"'"'s evoked response based on said comparison.
