Surround-induced foveal afterimage pulsation: Evidence for a long-range neural effect
چکیده انگلیسی

We demonstrate that an afterimage resulting from a strong foveal light flash can be made to pulsate by luminance modulation of a surrounding annulus as far as 8 deg away. Afterimage pulsation persists even if all artifacts due to pupil size, stray light and simultaneous contrast are ruled out. This suggests an origin by a long-range neural process acting from the remote surround. The effect is interpreted in terms of an adaptive gain control optimizing the responses of visual cells.
