我们研究了家禽雏鸡如何区分具有共同方向的线条纹理和不同方向的线条纹理。通过调节刺激颜色和光照来选择性地刺激不同的受体机制。雏鸡能分辨消色差纹理，但不能分辨长波和中波色差纹理，也不能分辨短波和超短波色差纹理。这些结果表明，线的方向检测和纹理识别使用的消色差信号要么来自双视锥，要么来自长和中波长敏感的单视锥的总和输出。(C) 2003 Elsevier Ltd.版权所有。
We investigated how poultry chicks discriminate textures of lines sharing a common orientation from textures of variably oriented lines. Stimulus colours along with illumination were adjusted to selectively stimulate different receptor mechanisms. Chicks could discriminate achromatic textures, but not textures isoluminant to the double cones that gave a long vs. medium wavelength chromatic signal, nor an intensity signal for the short and very-short wavelength cones. These results suggest that detection of line orientation and texture discrimination uses an achromatic signal derived either from the double cones, or summed outputs of long and medium wavelength sensitive single cones.
