| Abstract(in English) | We report extremely long-range interaction between two Gabor signals (GSs) up to 10-degree separation when they were presented at mirror symmetrical locations in the left and right visual fields. Contrast detection threshold of a GS probe reduced considerably (facilitation) when GS cue and probe subtended the same degree of visual angle to the left and right symmetrical positions from the vertical meridian as compared to when no cue was presented (control). No facilitation was found when the GS cue was presented at left-right asymmetric locations or when the cue orientation differed more than 30 degrees from the probe. Furthermore, there was no facilitation with top-bottom symmetrical configuration. These results demonstrate that the interaction is specific to orientation and direction across the vertical meridian. The existence of such extremely long-range interaction suggests that the symmetrical facilitation is achieved via higher level processing beyond V1. |
