Movement adaptation in the visual evoked response.
Visual evoked responses to sinusoidal movement before and after adaptation to linear movement were compared. Fourier analysis indicated that the responses evoked by sinusoidal movement were insensitive to direction of movement. Following adaptation, the harmonics describing the waveforms changed in magnitude and phase, and showed an asymmetry of waveshape not evident before adaptation. The data are consistent with the existence of movement-sensitive cells within the intact visual system which change in response characteristics as a result of adaptation to linear movement.
