      A LOT!! Scientists believe its to be about 100 billion; which is 100,000,000,000 if written out. And we still have no clue how most of the brain works! No wonder!

      No clue!!! that’s a bit Harsh, I would think they have some ideas…. 100,000,000,000 that is a lot. Although, I think there is also over a trillion (a lot of zeros) synapses in the brain. These are like little switches that release and then take up chemicals and are responsible for things like thoughts, feelings and pain. Although how the trillion synapses interact to create thoughts, feelings and pain for example I have no idea..
