title: [Age-related features of the working capacity of rats during positive emotional reinforcement by hypothalamic self-stimulation].
abstract: Some age-related peculiarities found in rats striving for hypothalamic self-stimulation: (1) the capacity in old rats decreased more rapidly during fatique than in adult ones; (2) some old but not adult animals died after hard physical work; (3) some old rats "working" for a longer time have done greater work, than adult ones.
