Method and apparatus for treating a neurological disorder

A method of reducing anxiety in a subject, the method comprising:

• providing an audio input to the subject, the audio input comprising a sequence of tones in a frequency range comprising about 100 Hz to about 8000 Hz;
• adapting intensities of the audio input to audiometric parameters of the subject;
• producing a plurality of actuation signals correlated with the audio input, wherein an onset of the plurality of actuation signals has a delay in the range of−500 ms to +500 ms relative to an onset of the correlated audio input;
• delivering an actuation signal of the plurality of actuation signals to each of a plurality of electrodes in contact with a tissue surface of the subject's body to provide tactile stimuli to the tissue surface;
• and
• reducing anxiety in the subject.
