Psychiatrist Dr Karen Norberg, of the National Bureau of Economic Research in Cambridge, Massachusetts knitted this awesome, anatomically correct replica of the human brain.
Using different colour to represent different parts of the brain, it took Dr. Norberg one year to complete her project. She used yarn because she thought “the wool lent itself to creating the right “rippling” effect for parts of the brain and was easier to manipulate than other materials.”
The frontal cortex is cream and pale green, the visual cortex a mix of blue, purple and turquoise while the hippocampus is made up of baby pink wool. The two sides of the nine inch brain - one and a half times life size - are joined together by a zip with the cerebellum knitted in blue and spinal cord trailing off in white strands of wool.
According to Dr Norberg the project was a labour of love:
"For me, there were two humorous aspects. One was simply to undertake such a ridiculously complex, time consuming project for no practical reason. The second was the idea of making a somewhat mysterious and difficult object - a brain - out of a ‘cuddly’, cheerfully coloured, familiar material like cotton yarn."
The wonderful woolly brain is currently on display at the Boston Museum of Science.
