The mesopic range, defined for cats with fully dilated pupils, extends from -1.0 to +1.4 log cd/m(2). The technique employed involves measurement of the relative shift in threshold with adaptation level, between two wave-lengths respectively selective for cones and rods at threshold. The magnitude of this shift is compared with that predicted from the Dartnall nomogram for visual pigments 556 and 507 (the in situ cone and rod absorption maxima).2. The result is based on monochromatic increment threshold determinations for 149 on-centre or off-centre fibres, isolated in the optic tract posterior to the chiasma, under a variety of adaptation levels. All units included receive dual input - from 500 nm rods and from a single class of cones with maximum sensitivity at 556 nm. No units receive input from 450 nm cones; six units with input mediated purely by rods are excluded from the sample.

对于瞳孔完全扩张的猫所定义的中间视觉范围，从-1.0至+1.4 log cd/m²。所采用的技术涉及测量在阈值时分别对锥体细胞和杆体细胞有选择性的两个波长之间，阈值随适应水平的相对变化。将此变化的幅度与根据达特纳尔视觉色素556和507（原位锥体细胞和杆体细胞吸收最大值）列线图预测的值进行比较。2. 结果基于在多种适应水平下，对149条位于视交叉后方视束中分离出的中心或周边纤维的单色增量阈值测定。所有纳入的单位均接受双重输入——来自500nm的杆体细胞和来自一类在556nm具有最大敏感性的锥体细胞。没有单位接受来自450nm锥体细胞的输入；样本中排除了六个仅由杆体细胞介导输入的单位。
