This important study examines the stability and compensatory plasticity in the retinotopic mapping in patients with congenital achromatopsia. It provides convincing evidence for a stable mapping of the visual field in V1, alongside changes of the readout from V1 into V3, which shows revised receptive field location and size. With the controlling for potential confounding variables, this paper would be of interest to scientists studying the visual system, brain plasticity, and development.
