SUMMARY:The wonder of hue:  the non-monotonic contribution of S-cones to b
 lueness - Sungmi Oh\, Joshibi University\, Japan

DESCRIPTION:One of the fundamental problems in colour vision research is t
 o understand how the signals from the 3 cone classes encode hue. The preva
 iling view has been that each cone type monotonically contributes to hue s
 ensation on each spectrally opponent dimension. However\, complete descrip
 tion of the machinery is not yet available\, and an increasing number of r
 eports indicate cone signal behaviours that violate the classical opponent
  model. \nI will describe my work on the nonmonotonic contribution of the 
 S-cone signal to perceived blueness\, and its possible implications for th
 e circuitry of the early chromatic pathways.
