The possibility of the formation under chronic experimental conditions of a reaction of a selective character to species-specific acoustic signals (SAS) of the agonistic type, presented to cats against the background of subthreshold electrical stimulation of hypothalamic divisions, was demonstrated. Reactions appropriate to the SAS presented appeared only in those animals in which threshold electrical stimulation evoked directed aggressive reactions. Partial bilateral ablation of the sensorimotor region of the cortex (SMC) did not influence the selective character of the reaction to the SAS, but led to a change by comparison with the preoperative period in the relationship of the motoric and acoustic reactions of the agonist type to conjoint acoustic and electrical stimulation.
结果表明，在慢性实验条件下，当对猫进行下丘脑各分区的阈下电刺激时，呈现出具有选择性特征的对争斗类型的种属特异性声信号（SAS）的反应形成的可能性。仅在那些阈下电刺激能引发定向攻击反应的动物中出现了与所呈现的SAS相适应的反应。皮质感觉运动区（SMC）的部分双侧切除并未影响对SAS反应的选择性特征，但与术前相比，却导致了激动类型的运动和听觉反应与联合声电刺激之间关系的改变。
