title: [Dynamics of conditioned reflex preservation in young and adult rats].
abstract: 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.
