There is evidence indicating the existence of an innate migratory drive as well as genetic control of the onset, duration and end of the migration period, the amount of migratory activity, a genetically prescribed parameter that determines the distance over which the bird flies, the migration directions and physiological parameters, in particular fat deposition during the migratory period, but also those determining which individuals will migrate and which will not in forms that are obligatorily partial migrants.

有证据表明，存在某种先天的迁徙动因并涉及以下几方面的遗传调控：(1)迁徙过程的起始、持续以及结束；(2 )迁徙活动量，即决定鸟类飞行距离的遗传参数；(3)迁徙方向；(4)生理参数，特别是迁徙期间的脂肪贮存，以及对于那些部分个体迁徙的鸟种而言，决定个体迁徙与否的生理参数。

Both kinds of rats were inbred to construct the new inbred strains from Sprague-Dawley outbred strain background. In the first section, conventional visual electrophysiology was observed in CSNB and RCD rat.

在课题的第一部分，我们对这两种动物的视觉电生理性状进行了观察，包括：常规视觉电生理，CSNB大鼠的暗适应多焦点视网膜电图和明适应多焦点视网膜电图，RCD大鼠的不同颜色刺激光暗适应多焦点视网膜电图。
