Michael One receptor can't, but a matrix of many receptors can by very clever interpolation. Draw a grid of ten squares by ten squares. If you put different numbers in each square that will equal 100 pieces of information . Now do the same but with octagonal shapes instead. Same 100 pieces of information. Now draw a ruler down the square grid. Ten lines of information. Now draw a ruler down the octagonal grid and count the number of lines in which the information can vary. Each octagonal space can read back two pieces of information, across the centre and across the top of each shape. Now let us assume that the line across the top is "adjusted" to equal an average of all the adjoining receptors. This gives a new piece of information which is not based on the same interpolation as the square grid because in practice there are blank spaces between all the receptors. As a further test try drawing both the square and the octagonal grids with a 50% space between each one. This is a lot easier face to face with a piece of graph paper.
