The performance of rats with neurotoxic lesions of the dorsal ascending noradrenergic bundle (DB) was compared with that of sham-operated control animals under two behavioural conditions. Animals with DB lesions were slower than controls to acquire a classically-conditioned emotional response (conditioned suppression) with a trace interval interposed between the clicker conditioned stimulus (CS) and the shock reinforcer. However, if the latter half of the trace interval was filled by a second stimulus, a light, the DB-lesioned animals acquired conditioned suppression to the clicker faster than did controls under the same conditions. These results are discussed in terms of the attentional theory of DB function.
在两种行为条件下，对具有背侧上行去甲肾上腺素能束（DB）神经毒性损伤的大鼠与假手术对照动物的表现进行了比较。与对照动物相比，患有DB损伤的动物在习得经典条件性情绪反应（条件性抑制）时速度较慢，在点击条件刺激（CS）和电击强化刺激之间插入了一个痕迹间隔。然而，如果痕迹间隔的后半部分由第二个刺激（一个光）填充，那么在相同条件下，患有DB损伤的动物比对照动物更快地对点击器产生条件性抑制。根据DB功能的注意理论对这些结果进行了讨论。
