1. An in-ear stimulator for administering thermal stimulation to the ear canal of a subject, comprising:

  • (a) an earpiece configured to be at least partially insertable into the ear canal of the subject;

    (b) at least one thermoelectric device thermally coupled to said earpiece and configured to heat or cool said earpiece to thereby heat or cool the ear canal of the subject; and

    (c) a controller configured to deliver a time-varying thermal waveform to said at least one thermoelectric device such that said thermoelectric device effects corresponding temperature changes to said earpiece to deliver caloric stimulation to the subject, wherein the controller is configured to deliver the time-varying thermal waveform such that the time-varying thermal waveform comprises an amplitude that increases or decreases through a plurality of different temperature points over time.
