The number of inductions and the duration of tonic immobility (TI) was measured in Brown Leghorn hens which were either sham-operated or had total removal of the telencephalon. The overall duration of TI was shorter in sham-operated birds than in decerebrates. The duration of TI decreased significantly in both groups when they were given one trial daily for 7 consecutive days but this was not seen when the birds received 5 trials in rapid succession. The number of inductions necessary to produce TI in decerebrate hens did not differ significantly with repeated testing but sham-operated birds were less susceptible to induction by the 7th trial when tested daily. In contrast, testing the birds in rapid succession had no effect. The possible role of the telencephalon in TI was discussed.
在接受假手术或完全切除端脑的来航褐壳蛋鸡中，测量了强直静止（TI）的诱导次数和持续时间。假手术鸡的TI总持续时间比去脑鸡短。当两组鸡连续7天每天接受一次试验时，TI持续时间均显著缩短，但当鸡连续快速接受5次试验时，未观察到这种情况。去脑母鸡产生TI所需的诱导次数在重复测试时无显著差异，但假手术鸡在每天测试时，到第7次试验时对诱导的敏感性降低。相比之下，连续快速测试鸡则没有影响。讨论了端脑在TI中的可能作用。
