Visual feature-analyzers and aftereffects of tilt and curvature

Explains the aftereffect produced by viewing a line tilted in the frontal plane in terms of the adaptation of orientation-specific units in the visual system. This explanation is more successful than explanations based on "normalization" or "satiation." Aftereffects of curvature or median-plane tilt can be explained in analogous ways, although the visual system units necessary are in this case mainly hypothetical, since experiments capable of demonstrating the existence of these types of units have not yet been performed.
