Just how complex is your noggin?
Your brain synapses are actually more like individual microprocessors than simple on/off switches, and your brain has hundreds of trillions of them.
According to Stephen Smith, a Stanford professor of molecular and cellular physiology, the brain is vastly more intricate than we had ever imagined:
One synapse, by itself, is more like a microprocessor–with both memory-storage and information-processing elements–than a mere on/off switch. In fact, one synapse may contain on the order of 1,000 molecular-scale switches. A single human brain has more switches than all the computers and routers and Internet connections on Earth.
Yup, you’ve got the world’s craziest network right on top of yer shoulders.
