Materials and Method: A total of 30 hypothyroid patients of both sexes underwent polysomnography to assess sleep based on bioelectric potentials - electroencephalogram, electromyogram, and electrooculogram
The basic recordings included electroencephalogram (F3-A2, F4-A1, C3-A2, C4-A1, O1-A2, and O2-A1), electrooculogram
(EOG, LOC-A2, and ROC-A1), chin EMG, electrocardiogram, nasal-oral pressure transducer airflow, thermal oronasal airflow, thoracic and abdominal respiratory efforts, oxyhemoglobin saturation, snoring sound, and body position.
In the standard PSG record conducted, there are parameters from EEG, submental and tibia electromyogram, electrooculogram
(2 channels) and electrocardiogram, nasal airflow sensor, chest and abdomen movements sensor, body position sensor, tracheal microphone, and pulse oximeter.
The resulting electrical signal that can be obtained from this field is called Electrooculogram
The PSG recordings contain the ECG, EEG (C3-A2, C4-A1, O2-A1, O1-A2), electromyogram, electrooculogram
, blood oxygen saturation (Sa[O.
(EOG) was recorded from the medial upper and lateral orbitals of the right eye.
DWT-DCT-SVD based blind watermarking technique of gray image in electrooculogram
Kim Y, Doh NL, Youm Y, Chung WK (2007) Robust discrimination method of the electrooculogram
signals for human-computer interaction controlling mobile robot.
Four- channel electroencephalogram (EEG), electromyogram (EMG-submental and right-left tibialis), two-channel electrooculogram
(EOG - right-left), electrocardiogram (ECG), nasal airflow, thorax and abdominal respiratory movements, pulse oximetry, blood oxygen saturation and body position data were recorded throughout the night during PSG.
While each participant watched 40 music video excerpts of one-minute duration each, 32-dimensional EEG signals using 10-20 international system  and various peripheral physiological signals--Galvanic skin response (GSR) , respiration amplitude, skin temperature, electrocardiogram (ECG) , blood volume by plethysmograph, electromyograms of Zygomaticus and Trapezius muscles (EMG) , and electrooculogram
(EOG) , skin temperature and respiration--were collected.
Another electrode was placed above the right eye to record the electrooculogram
