Differences between M.M. and controls were also seen in brain scans. Typically, the ventral visual cortex shows different patterns of activity depending on whether you are viewing a face, an object, or a scene – but M.M. didn’t seem to have developed the necessary networks.

The brain’s data compression mechanisms

Researchers have hitherto assumed that information supplied by the sense of sight was transmitted almost in its entirety from its entry point to higher brain areas, across which visual sensation is generated. “It was therefore a surprise to discover that the data volumes are considerably reduced as early as in the primary visual cortex, the bottleneck leading to the cerebrum,” says PD Dr Dirk Jancke from the Institute for Neural Computation at the Ruhr-Universität. “We intuitively assume that our visual system generates a continuous stream of images, just like a video camera. However, we have now demonstrated that the visual cortex suppresses redundant information and saves energy by frequently forwarding image differences.”
