Amphetamine-induced stereotyped behavior is a nonsteady oscillatory process with minute fluctuations rate of head turnings. After acute amphetamine stereotypy have lower amplitude and limited rhythmicity in pinealectomized rats as compared with intact animals. Pinealectomy also delayed tolerance after chronic administration of amphetamine (5 mg/kg/day, 14 days) without usual decrease number of short period (2-3 min) fluctuations in time course of stereotypy.
苯丙胺诱导的刻板行为是一种不稳定的振荡过程，头部转动的波动频率微小。与完整动物相比，松果体切除的大鼠在急性苯丙胺诱导的刻板行为后振幅较低且节律性有限。松果体切除还延迟了慢性给予苯丙胺（5毫克/千克/天，14天）后的耐受性，且在刻板行为的时间进程中，通常短周期（2 - 3分钟）波动的数量没有减少。
