Tonic immobility in chickens was affected by a variety of drugs that act on monoaminergic systems. Compounds that enhanced the duration of tonic immobility were d-LSD, BOL-148, pargyline, and iproniazid; 5-hydroxytryptophan, p-CPA, and atropine had no effect. Injections of serotonin depressed response duration. A suggestive parallel was noted between the results of the present study and those of previous work reporting drug-induced suppression of raphe electrical activity. The data appear to implicate monoamines, especially serotonin, in the mediation of behavioral activation and suppression.
鸡的紧张性不动受多种作用于单胺能系统的药物影响。能延长紧张性不动持续时间的化合物有d - LSD、BOL - 148、帕吉林和异烟肼；5 - 羟色氨酸、对氯苯丙氨酸和阿托品则无作用。注射血清素会缩短反应持续时间。本研究结果与先前报道药物诱导中缝电活动抑制的研究结果之间存在明显的平行关系。数据似乎表明单胺，尤其是血清素，参与了行为激活和抑制的调节。
