• Bistable Gestalts reduce activity in the whole of V1, not just the retinotopically predicted parts, de-Wit et al. (2012). Journal of Vision. Outcome recorded: mixed. Here we replicate this reduced V1 response, but find that the modulation in V1 (and V2) to the perceived organization of the input is not specific to the retinotopic location at which the sensory input from that stimulus is represented. Instead, we find a response modulation that is equally evident across the primary visual cortex. Thus, the perception of an organized Gestalt causes a broad feedback effect that does not act specifically on the part of the retinotopic map… Outcome read from the full text. View paper
