How complex could the human brain be?


Well, here is a tiny piece of a MOUSE brain:

Researchers at Stanford University School of Medicine using array tomography imaging were able to see tissue samples from a mouse brain that had been bioengineered to make larger neurons in the cerebral cortex express a fluorescent protein (found in jellyfish), making them glow yellow-green. The glow made it possible to see synapses against the background of neurons.

According to a Health Tech article at cnet news
 (http://news.cnet.com/8301-27083_3-20023112-247.html)
there are about 200 billion nerve sells connected to one another via hundreds of trillions of synapses with each synapse functioning like a microprocessor which collectively (tens of thousands of them) connect to a single neuron to other nerve cells. In the cerebral cortex alone there are as many synapses as there are stars in 1,500 Milky Way galaxies. One synapse may contain 1,000 molecular-scale switches.  Put another way, a single human brain has more switches than all the computers and routers and internet connections that exist on Earth.

To me, this information is stunning and implies that the complexity and number of things that go on in a person’s brain is far beyond our capability to presently understand! Indeed, it is beyond belief!

When I think about the above in context with the premise that there is a lot going on when we engage stereovision… It would appear that we grossly underestimate the number of things we should be considering!

Thank you to Professor Dominick Maino for bringing this to my attention in his blog!

This information is stunning and I suspect many people just won’t give it the consideration it deserves.
