In the Doll's Eyes Test, what is a normal eye movement when the head is rotated?

Explanation:
This tests the vestibulo-ocular reflex through the Doll’s Eyes phenomenon. When the head is rotated, a normal, intact brainstem causes the eyes to move in the opposite direction to keep gaze fixed on a target. This opposite movement confirms that the reflex pathways from the inner ear through the brainstem to the eye muscles are functioning. If the eyes instead move with the head or don’t move, that suggests the reflex is impaired, indicating potential brainstem dysfunction. Therefore, the normal response is the eyes deviating to the opposite direction of head rotation.
