Baseler, H.E., Brewer, A.A., Sharpe, L.T., Morland, A.B., Jägle, H. and Wandell, B.A. (2002) Reorganization of human cortical maps caused by inherited photoreceptor abnormalities. Nature Neuroscience, 5 (4). pp. 364-370. ISSN 1097-6256
We describe a compelling demonstration of large-scale developmental reorganization in the human visual pathways. The developmental reorganization was observed in rod monochromats, a rare group of congenitally colorblind individuals who virtually lack cone photoreceptor function. Normal controls had a cortical region, spanning several square centimeters, that responded to signals initiated in the all-cone foveola but was inactive under rod viewing conditions; in rod monochromats this cortical region responded powerfully to rod-initiated signals. The measurements trace a causal pathway that begins with a genetic anomaly that directly influences sensory cells and ultimately results in a substantial central reorganization.
