Question: How Many Nuerons Does the average human have?

Keywords: , ,

  1. There are about 100 billion neurons in the brain alone of an average adult. I guess that makes the answer a lot.


  2. Hi Jamesy.

    Yeah 100 billion sounds about right.

    That is this many 100,000,000,000

    This is also very similar to the number of galaxies in the universe


  3. Hey @jamesy. James and Dustin are right. It is also estimated that the human nervous system in total has as many as 1000 billion neurons, central and peripheral nervous system.


  4. Nice question, Jamesy.
    Thanks, everyone – I learnt something new here! I knew there were loads, but I had no idea how many. 🙂
