"To explain all nature is too difficult a task for anyone man or even
for anyone age. Tis much better to do a little with certainty, and leave
the rest for others that come after you, than to explain all things ...
" Sir Isaac Newton (1642-1727) This book describes and discusses some
new aspects of col- or vision in primates which have emerged from a
series of experiments conducted over the past 8 years both on single
ganglion cells in monkey retina and on the visually evoked cortical
potential in man: corresponding psychophysical mechanisms of human
perception will be considered as well. An attempt will be made to better
understand the basic mechanisms of color vision using a more
comprehensive approach which takes into account new mechanisms found in
single cells and relates them to those found valid for the entire visual
system. The processing of color signals was followed up from the retina
to the visual cortex and to the percepq.tal centers, as far as the
available techniques permitted.
