THE UNINTERRUPTED COMMUNICATIONS NETWORK

IN THE BODY

Neurons perform communication in the body by means of a unique method, involving
electrical and chemical processes of extraordinary complexity. In this way is estab-
lished a flawless coordination, both inside the brain and between the brain and the oth-
er organs. While you perform movements that appear exceedingly ordinary—such as
holding this book in your hand, turning its pages or casting your eyes over the words—
a dense communications traffic takes place in your body’s nerve cells. The more closely
one examines the neural network that gives rise to this extraordinary communications,
the better their miraculous creation can be understood.
The way the nerve cells establish uninterrupted communications, even without touch-
ing one another, is of the greatest importance in maintaining the body’s functions.
When you look at this book, for example, if the signals belonging to the image re-
mained in the first nerve cells in your retina and never reached your visual center at
the rear of the brain, then you would never perceive any images of the external world.
However, we do perceive images, uninterruptedly and with no gaps
between them, as a result of God’s compassion.
