What happens to the channels when a patient looks right?

When a patient looks to the right, the channels recorded in a system, commonly used in sleep studies or eye movement tracking, will demonstrate specific movement patterns corresponding to the direction of the gaze. In this case, when a patient looks right, the channels reflecting eye movements will move toward each other.

This movement occurs because, during right gaze, the corresponding eye (right eye) moves laterally to the right, which can cause the signal for that channel to become more pronounced or elevated, while the signal for the opposite eye may decrease. This dynamic interaction results in the two channels appearing to converge toward each other, illustrating the activity of each eye's movement relative to the other as the patient gazes to the right. Understanding this movement is crucial for interpreting data in various contexts, including sleep research and neurological assessments.
