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.”
