摘要

在辐射迷宫中，暴露于0.5 Gy电离辐射和短期固定应激的大鼠表现出中枢神经系统激活并伴有工作记忆减少的现象。与压力相比，辐照会导致探索性活动抑制，从而导致任务完成的一定自动性。暴露于辐照后的情绪应激显著改变了大鼠的表现，引起中枢神经系统抑制和长期记忆下降。

[The dynamic behavioral characteristics of rats in a maze after isolated and combined exposures to ionizing radiation and psychoemotional stress].

Rats exposed to ionizing radiation (0.5 Gy) and short-term immobilization stress displayed CNS activation accompanied by diminution of working memory when tested in radial maze. Irradiation, as compared to stress, caused exploratory activity inhibition that led to certain automatism in task fulfillment. Exposure to emotional stress after irradiation modified significantly rat performance causing CNS inhibition and long-term memory decline.
