Experimental data are presented on the formation and retention during 24 hours of a motor alimentary conditioned reflex (MCR) in a T-maze, in rats 4--5 months and 1,5--2 months old. In adult rats the formation of MCR required a significantly smaller number of runs and less time, than in young ones. In young animals reflex retention is better as compared to adults. Traces of MCR change regularly throughout 24 hours in both animal groups which may be due to development of memory in several stages, in young animals this process being slower.
本文给出了4至5月龄和1.5至2月龄大鼠在T型迷宫中形成和保持24小时运动性食物条件反射（MCR）的实验数据。与幼鼠相比，成年大鼠形成MCR所需的跑动次数明显更少，时间也更短。与成年动物相比，幼龄动物的反射保持情况更好。在两组动物中，MCR的痕迹在24小时内都有规律地变化，这可能是由于记忆在几个阶段的发展，幼龄动物的这个过程较慢。
