Electroencephalogram (EEG) recordin

Electroencephalogram (EEG) recordings were made with a Neuroscan SynAmps2 Amplifier (Scan 4.5, Neurosoft Labs, Inc., Virginia, USA) and a 64 Ag/AgClelectrode cap, using the left mastoid as a reference. The EEG data sampling rate was500 Hz. During the experiment, the electrode impedance was kept below 5 KΩ, and thehorizontal electrooculogram (EOG) and vertical EOG were simultaneously recorded.All EEG data were analyzed off-line. The EEG was digitally filtered with a low-passfilter at 30 Hz (24 dB/Octave) and extracted from -200 to 800 ms time-locked to theonset of S2, with the prestimulus period as baseline. Ocular artifacts were corrected,and other artifacts with peak-to-peak deflection exceeding± 80 μV were excluded. Theaverage EEG was analyzed separately for the UP and HP conditions.

腦電圖 （EEG） 記錄是使用神經掃描合成安培進行的
2 個放大器（掃描 4.5，神經軟實驗室，美國弗吉尼亞州）和 64 Ag/AgCl
電極蓋，使用左桅杆作為參考。腦電圖資料抽樣率為
500 赫茲。在實驗過程中，電極阻抗保持在5 KΩ以下，並且
同時記錄水準電圖（EOG）和垂直EOG。
所有腦電圖資料均線上分析。EEG 通過低通式數位過濾
30 Hz （24 dB/Octave） 濾波器，從 -200 到 800 ms 時間鎖定到
S2 的開始，以預刺激期為基線。眼部偽影被糾正了，
和其他峰峰值偏轉超過±80μV的偽影被排除。的
根據 UP 和 HP 條件分別對平均 EEG 進行分析。

腦電（EEG）記錄是用一個神經叢做的
2個放大器（掃描4.5，Neurosoft Labs，Inc.，Virginia，USA）和64 Ag/AgCl
電極帽，以左乳突為參照。腦電圖數據取樣速率為
500赫茲。在實驗過程中，電極阻抗保持在5kΩ以下
同時記錄水准眼電圖和垂直眼電圖。
所有腦電圖數據均離線分析。腦電圖用低通數位濾波
濾波器頻率為30赫茲（24分貝/倍頻程），選取時間為-200至800毫秒，鎖定至
以刺激前週期為基線，出現S2。矯正了眼部偽影，
排除其它峰間偏轉超過±80μV的偽影。這個
分別對uph和HP患者的平均腦電圖進行分析。
