Abstract

Within the first days after birth, the sleeping rats demonstrate the high rate of motor reactions (RMR) of the jerk type. With advancing age the RMR diminishes. However during a sudden change in the growth, the 25-day-old rats show an increase in the RMR of the jerk type. This is manifested by the return of the functions to the state marking the first days of life. The catecholaminergic mechanisms of the growth and development of rats are discussed.

摘要

在出生后的头几天内，睡眠中的大鼠表现出较高频率的抽搐型运动反应（RMR）。随着年龄的增长，RMR会降低。然而，在生长突然变化期间，25日龄的大鼠抽搐型RMR会增加。这表现为各项功能恢复到标志着生命最初几天的状态。文中讨论了大鼠生长发育的儿茶酚胺能机制。
