Brain knows how to use Diversity

Like snowflakes, no two neurons are exactly alike, But it’s not the size or shape that sets one neuron apart from another, it’s the way it responds to incoming stimuli. Carnegie Mellon university researchers discovered that diversity is vital to comprehensive brain function. Their research published in Nature Neuroscience.
Typically neuroscientists average to obtain their results, assuming that the variability is a “bug of biology"
“When we think about computer chips, variability in hardware clearly can be very destructive. Manufacturers spend a lot of time and expense making sure each processor on a chip is identical,” Urban said. “The brain is considered to be one of the most sophisticated computers there is. We were intrigued by the idea that the brain might make use of the messy, complex nature of its biological hardware to function more efficiently.”
