For comparison, new the supercomputer being installed at Argonne Labs operates at 1 exaFLOPS and comes with no software. Collectively, my estimate above based on common google searches is 700 exaFLOP per second. Each neuron operates once every 10 ms or 100 times per second, or 700 * 10^15 or 700 quintillion operations per second.įurthermore, the chemical connection between neurons are effectively "analog", or floating-point, so the correct term isn't "bits per second" but FLOPS. How many nerves are in the human body? Even an estimate of 10^11 (100 billion) neurons times an average of 7000 dendrites or 7.0 * 10^4 connections is 7.0 * 10^15 (7,000,000,000,000,000) or 7 quintillion neural connections. The numbers appear to be alarming, as approximately 50,000 neurons are lost a day. When one approaches the age of 20, one begins to lose neurons.
A figure that if we add it up, a year represents the loss of more than three and a half million. You really need to include the entire nervous system's number of nerves to truly appreciate the processing power of the human neural network. How many brain cells do you lose in a day People can lose about 10,000 neurons every day. Posts with unsourced content may be edited or deleted. Want to improve this post?
