Jack has been reading all sorts of other information about the brain (which seems to be because he is so worried about me). He has come up with some fascinating nuggets of information:
“the cerebral cortex contains approximately 14–16 billion neurons…the estimated number of neurons in the cerebellum is 55–70 billion…”– WIKIPEDIA (Brain)
Apparently, if you lived for eighty years, you would have lived for 2.5 billion seconds. Which perhaps gives us a little help in contemplating all of those billions of neurons. Our Milky Way galaxy is estimated to contain over 100 billion stars.
Each neuron is connected to other neurons….several thousands of other neurons…by means of connections called “synapses”.
“…the human brain has been estimated to contain approximately 100 trillion synapses…”
But I am sure…that your brain is to you more than some big figures…lots of zeros. Your brain contains the universe with you…all of your memories, the passions, the dreams…things that are incredibly precious to you.
I just wish my brain was not such a worry. It is such a astonishing object – nothing in the universe has been found to compare with the human brain. So, it would be nice if mine would behave!!!
