For every action and thought, signals travel along the nerve axons
extending from the brain to the muscles. Sodium channels in the axon
membranes open and close; sodium and potassium pumps regulate the
electrical energy balance in every cell membrane. Signals are deposited

at the synapses at the ends of the axons, and the neurotransmitters per-
mit communication between the axons. Muscle fibers, on the other hand,
perform the joint action of a million connections making five circuits a
second. In this way the necessary power is produced for you to tense
your arms, move your head from right to left, hum a tune and wiggle
your fingers and toes. The relevant muscles are permitted to contract,
but neither too much nor too little. The way that these can all be carried
out in great harmony simultaneously is of vital importance, even if
many are unaware of that.
About to cross the street, you turn your head to check the traffic,
step forward with your leg muscles, and analyze the time it will take ap-
proaching cars to reach you. You then turn your head to check the traffic
coming from the other direction.
And at that point, you hear a familiar voice, one you recognize,
from across the street. You compare that voice with records in the other
regions of your brain. The face, identity and name of the speaker all
come into your mind together. Adjusting the tension in your vocal cords
and the shape of your lips, you call that person by name. You wave a
greeting with your hand, while crossing the street safely, and then shake
the person’s hand.
Thanks to your brain’s ability to process parallel information, you
can perform all these actions at once. The brain does this millions of
times a day while you are awake, without your giving any special con-
sideration to how all this comes about.
When you are cold and feel that the air has become chilly, several
of your organs are affected by this change. A series of activities sponta-
neously go into action. Tiny pores in your skin and the outermost blood
vessels contract. The muscles tremble, helping maintain normal body
