Summary of the orientation selectivity and color selectivity of neurons

Orientation selectiveColor selective
Cells responsive to the surface stimulus in BE-viewing3/6  (50%)5/5  (100%)
Cells unresponsive to the surface stimulus in BE-viewing16/23  (69.6%)10/16  (62.5%)
  • Frequencies of the cells exhibiting selectivity (selectivity index > 0.5; p < 0.05, ANOVA) for orientation and color are shown. Frequencies of the cells responsive and those unresponsive to the surface stimulus in BE-viewing are indicated separately.
