Researchers at the Stanford School of Medicine attempted to measure the computational power of the combined synapses in the typical human brain. Lead researcher Stephen Smith wrote:

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.
