Researchers at the Stanford University School of Medicine developed three-dimensional technology with high resolution called array tomography. They tested this technology on mouse brain tissue. They was able to observe brain synapses in the great detail and found out that synapses are perhaps like microprocessors.
"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."
Their work appeared in the journal Neuron last week.
