“Drawing on the right side of the brain: A voxel-based morphometry analysis of observational drawing” asserts that artists may have increased neural matter in the parts of their brains that deal with visual perception, spatial navigation and fine motor skills. Huffington Post-Apr 22, 2014
Goofy sort of research with elements of prank, but plausible enough to get a headline. It isn’t surprising that the physique of the athlete is generally superior to the average office worker. Athletes at all levels work their bodies in all sorts of ways beyond just practicing the skill-set for their particular sport to achieve a condition simply called ‘shape’. You can spot them in the supermarket loading up on bulk protein, a toned outline under tight skin, and maybe they inspire better choices among the rest of us, more fruit and less cake. Doing a brain-scan isn’t so convenient and even if it was true it would be beside the point. Of course the brains of artists are different because they ‘train’ -- they look at stuff. Does it make their brains bigger -- who cares? The fact is they see more and anybody can.
To do it requires no sweat but it does take energy. One has to apply consciousness to mundane surroundings wherever one happens to be, and a surprising thing begins to happen. It’s been widely reported -- the more you look the more you see. Vision becomes “the only form of eating that produces its own meat”, a translation I’m sure but the intent is clear. The difference between the perception of an artist and coequally the viewer of art, and the rest of the population can’t be seen externally but it’s there. They’re seeing more in the same places. Their perceptions are in shape.
