Bilateral lesions of the locus coeruleus (LC) markedly increased susceptibility to the cateleptogenic effects of neuroleptics. The apomorphine-induced stereotypy was enhanced in rats with lesioned LC whilst amphetamine stereotypy was only slightly increased. No changes in locomotor activity have been observed in LC-lesioned rats treated with apomorphine and amphetamine. This data indicates that lesions of the LC produce decreased activity of dopaminergic brain neurons as well as supersensitivity of dopaminergic receptors.
蓝斑(LC)的双侧损伤显著增加了对神经阻滞剂致僵效应的易感性。在LC损伤的大鼠中,阿扑吗啡诱导的刻板行为增强,而苯丙胺刻板行为仅略有增加。在用阿扑吗啡和苯丙胺治疗的LC损伤大鼠中,未观察到运动活动的变化。该数据表明,LC损伤导致多巴胺能脑神经元活性降低以及多巴胺能受体超敏反应。
