First we hear that your brain is as unique as your fingerprints. Now we hear that much 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." According to researchers at Carnegie Mellon University, this diversity is critical to overall brain function and essential in how neurons process complex stimuli and code information. Estimates say that the human brain alone has upwards of 100 billion neurons, and that the brain itself is considered to be one of the most sophisticated computers that exists. Now researchers say every neurons (chip?) is unique? Check out the report for yourself.
