A device for delivering caloric vestibular stimulation to an individual, includes: (a) an earpiece configured to be at least partially insertable into the ear canal of the individual for delivering said caloric vestibular stimulation； (b) a power supply operatively associated with said earpiece； and (c) a controller operatively associated with said power supply and said earpiece for configuring said caloric vestibular stimulation as at least a first and second time-varying waveform. Preferably, the waveforms are actively controlled waveforms.
