            our  victories  and  defeats?  What  makes  us  resonate  with  the  beauty  of  a  flower,
            touched with morning dew, its petals shimmering like jewels in the rays of the rising
            sun;  or  the  gusting  of  the  wind,  the  singing  of  birds,  the  whisper  of  leaves,  the
            buzzing of bees hastening nectar-laden to their hive? All of these and much more —
            everything we see, hear and feel, every day, every hour, every moment of our lives, is

              recorded in our book of life by that tireless chronicler — the brain.
                  But where and how is it all being recorded? Where is all that information being
            stored,  and  by  what  inexplicable  manner  does  it  emerge  from  the  depths  of  our
            memory  in  all  its  vividness  and  vibrancy  of  color  —  virtually  materializing  in
            primordial form — those things we thought were long gone and forgotten? By way of

              clarification, let us start by seeing what kind of information enters our brain.
                  All humans possess sense organs such as eyes, ears, taste buds, etc., as well as
            various types of receptors over the entire body surface, i.e., nerve endings responding
            to  various  external  stimuli  such  as  heat,  cold,  electromagnetic  waves,  as  well  as
            mechanical and chemical effects. Let us examine the kinds of alterations these signals

              undergo before reaching the brain cells.
                  Let  us  take,  for  example,  eyesight.  Sunlight  reflected  from  an  ambient  object
            falls upon  our  light-sensitive retina. The  image  of the  object  reflected by the  light
            then  enters  the  retina  through  a  crystalline  lens,  which,  in  turn,  focuses  it  on  the

            retina.  The  latter  possesses  specialized  photoreceptor  cells,  called  rods  and  cones.
            Rods respond to low -level illumination, enabling one to see in the dark, and also
            provide  a  black  and  white  image  of  the  object.  By  contrast,  cones  respond  to  an
            optical spectrum of brightly illuminated objects. That is, the  cones absorb photons,
            each of which has a characteristic color — red, orange, yellow, green, blue, indigo or
            violet.  Further,  each  of  these  specialized  cells  "receives"  its  own  fragment  of  the
            object's image. Actually, the full image is broken up into millions of fragments, with
            each specialized cell picking up one piece of the whole picture (see Fig. 70).
