Psychiatrist and epidemiologist Karen Norberg knitted this anatomically correct replica of the human brain (1½ times life size) using different colored yarn to represent different regions. The frontal cortex is cream and pale green. The visual cortex is a mixture of blue, purple and turquoise. The hippocampus is pink.
The two hemispheres of the 9-inch brain zip together with the cerebellum knitted in blue. The spinal cord trails off in white strands of wool.
