tains a large number of proteins. A scent molecule can attach to one of
the protein molecules in these nerve cells for as long as its form dictates.
An electrical polarization thus results in this region, which gives rise to
electrical signals that reach the scent perception region immediately be-
neath the forehead. Here the information from the different cells is ana-
lyzed, and the source of the scent is determined when they are sent to
various brain structures. (For details, see Harun Yahya, The Miracles of
Smell and Taste.)
You are indebted to the sensitive structure in your nose for your
ability to enjoy the smells of newly baked bread, the roses in the garden,
new-mown grass, soil after rain, hot soup, strawberries, parsley, the
soap you use or shampoo. Most people never stop to think about how
many scents they detect each day and how an image of their origin
forms in the mind, thanks to these scents. Yet your sense of smell is one
