The brain may be an even more powerful computer than before thought — microscopic branches of brain cells that were once thought to basically serve as mere wiring may actually behave as minicomputers, researchers say.
The most powerful computer known is the brain. The human brain possesses about 100 billion neurons with roughly 1 quadrillion — 1 million billion — connections known as synapses wiring these cells together.
Neurons each act like a relay station for electrical signals. The heart of each neuron is called the soma — a single thin cablelike fiber known as the axon that sticks out of the soma carries nerve signals away from the neuron, while many shorter branches called dendrites that project from the other end of the soma carry nerve signals to the neuron.
Now scientists find dendrites may be more than passive wiring; in fact, they may actively process information.
