简要总结
This is a prospective, non-randomized study designed to generate preliminary data to assess the effect of a new portable non-invasive caloric stimulator on EEG waveform and cerebral blood flow on normal healthy volunteers.
详细描述
Study activities include monitoring with bilateral transcranial Doppler (TCD), EEG and continuous EKG monitoring at 30 second intervals for 5 minutes. This is followed by placement of the caloric stimulator investigational device for 20 minutes. An additional 20 minutes of TCD and EEG monitoring will also be recorded. This will end study participation.

结局指标
主要结局
Changes in cerebral blood flow
时间窗: 20 minutes
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.
次要结局
- Alterations in EEG readings(40 minutes)
- Alterations in regional cerebral brain flow (rCBF)(40 minutes)
