Simple problem, complex solution

Understanding the human brain is a formidable task. Parked inside
the average cranium are between 1 and 10 billion neurons.
Extensions called dendrites relay electrical impulses to other
neurons, the brain cells that serve as the basic building blocks
of thought and activity. The electrical impulses are carried on
fibers called axons. The result is a neural network of remarkable

The power of neurons is that they can work together in different
ways to produce speech, vision, hearing, and thought. Only when
something goes terribly wrong are we aware of how serious it is to
lose these connections. Only then are we able to recognize how
difficult it is to regain what's lost and how much therapy may be
