Outcome Measures
Primary Outcomes (1)
Changes in cerebral blood flow
Changes in cerebral blood flow will be quantified through the use of bilateral transcranial Doppler (TCD). The baseline TCD of three vessels will be compared with measurements taken at 30 second intervals for 5 minutes after caloric stimulation.
20 minutes
Secondary Outcomes (2)
Alterations in EEG readings
40 minutes
Alterations in regional cerebral brain flow (rCBF)
40 minutes
Interventions
Non-invasive neurostimulator used for up to 20 minutes in a session.
