There are more possible ways to connect the brain’s neurons than there are atoms in the universe.
JOHN RATEY (2001)
As scientists have begun to understand the mechanics of the brain they have discovered a world of almost unimaginable complexity.6 The brain has around 100 billion neurons. Each neuron may have up to 100,000 dendrites (think of dendrites as roots—they gather information for the neuron) and one axon (think of the axon as a tree trunk, passing on information). The connections between our neurons, connected by the dendrites, are the maps that guide our thoughts, behaviors, and action.
If you want to determine how many possible ways the neurons in a brain could be connected, simply multiply the ...
