is a Turkish painter who has been blind since birth. His paintings are amazingly realistic, incorporating color, perspective, and great detail. To determine how this may be possible, Harvard neurologists Alvaro Pascual-Leone Amir Amedi are scanning Armagan's brain. From New Scientist:
Pascual-Leone and Amedi want to see what Armagan's brain can tell them about neural plasticity. Both scientists have evidence that in the absence of vision, the "visual" cortex - the part of the brain that makes sense of the information coming from our eyes - does not lie idle. Pascual-Leone has found that proficient Braille readers recruit this area for touch. Amedi, along with Ehud Zohary at the Hebrew University in Jerusalem, found that the area is also activated in verbal memory tasks.
When Amedi analysed the results, however, he found that Armagan's visual cortex lit up during the drawing task, but hardly at all for the verbal recall. Amedi was startled by this. "To get such extraordinary plasticity for [drawing] and zero for verbal memory and language - it was such a strong result," he says. He suspects that, to a certain extent, how the unused visual areas are deployed depends on who you are and what you need from your brain.
Even more intriguing was the way in which drawing activated Armagan's visual cortex. It is now well established that when sighted people try to imagine things - faces, scenes, colours, items they've just looked at - they engage the same parts of their visual cortex that they use to see, only to a much lesser degree. Creating these mental images is a lot like seeing, only less powerful. When Armagan imagined items he had touched, parts of his visual cortex, too, were mildly activated. But when he drew, his visual cortex lit up as though he was seeing. In fact, says Pascual-Leone, a naive viewer of his scan might assume Armagan really could see.
I asked Amy Parness, the co-founder of Sparkle Labs, maker of fantastic educational electronics kits, to write a Medium post about gender and the business of being a maker business person. Her terrific essay calls out the problems with “pink girly engineering kits.” From Medium:
Zero UI is the new term for “invisible interfaces”—what happens in the future when all the clicking and tapping and typing is history: “If you look at the history of computing, starting with the jacquard loom in 1801, humans have always had to interact with machines in a really abstract, complex way.” [Fast Company]
