I was pleased David Hubel was honoured by an obituary in The Telegraph, but I was surprised by the opening sentence: “When Hubel and Wiesel began experiments on vision and the brain in the late 1950s, neuroscientists thought that images from the retina were transmitted to visual centres in the brain, and projected onto the cerebral cortex in the same way as a photograph on to film.” Surely this underestimates 1950s neuroscience??
