        Figure  1.7.  A  simulated  spatiotemporal  cell  field  for  a  target  organ.  The
              affected  cells  are white  and  the  normal  cells  are  black;  some  repair  is
              taking place, as well  (from  Christakos  and  Hristopulos,  1998).

        Spatial  maps simulating cell distribution  at different  times  are shown in  Figure
        1.7.  Note  the  change  in  number  of  normal  cells  (black)  vs.  affected  cells
        (white)  in space/time  (some of the  affected  cells are repaired in time).  These
        maps  take  into  consideration  the  spatial  and  temporal  correlations  between
        cells.

               continent.  [From  Menozzi  et al,  1978;  ©1978  by AAAS,  reproduced

         EXAMPLE  1.9:  Genetic  distances  between  populations  can  be  mapped based
         on gene frequencies in human beings.  The  map in  Figure  1.8 shows a  systematic
         pattern that  slopes from the  Near  East and southeastern  Europe to  the  north-
         eastern  portions  of  the  European  continent.  The  more  dissimilar  the  shade,
