the vor gain ( eye velocity/head velocity , corrected for spontaneous nystagmus ) during rotations ( 30-300 degrees/s ) in the dark was diminished from nearly 1.0 preoperatively to approximately 0.5 when first measured after labyrinthectomy , except for rotations toward the lesioned side at high speeds for which the gain was even lower .
