Fear responses elicited by electrical stimulation in the dorsal and ventral hippocampus of cats, and the conditioned fear behavior established by pairing this stimulation with a neutral stimulus disappeared after bilateral ablation of the suprasylvian gyrus. The same reactions were not affected when the ectosylvian gyri were removed. The suprasylvian ablation did not impair conditioned classical defence reflexes when a noxious stimulation of the hind limb was used as an unconditioned stimulus. It is suggested that the suprasylvian association area plays an important role in fear produced by hippocampal stimulation but not in pain responses elicited by a noxious peripheral stimulus.
猫背侧和腹侧海马体中的电刺激引发的恐惧反应，以及将这种刺激与中性刺激配对所建立的条件性恐惧行为，在双侧切除上薛氏回后消失。切除外薛氏回时，相同的反应不受影响。当使用后肢的有害刺激作为非条件刺激时，上薛氏回切除并不损害条件性经典防御反射。研究表明，上薛氏联合区在海马体刺激产生的恐惧中起重要作用，但在有害外周刺激引发的疼痛反应中不起作用。
