Caloric responses for all subjects. Left ear irrigation is indicated by lighter gray bars, and right ear irrigation is indicated by darker (gray and black) bars. Peak slow phase velocities in deg/s are plotted. Negative velocities indicate leftward slow phase eye movement. LC, 24°C irrigation of the left ear; LW, 50°C irrigation of the left ear; RC, 24°C irrigation of the right ear; RW, 50°C irrigation of the right ear. The subject and week of testing are indicated. Negative weeks indicate presurgical data.
