[EFFECTS OF URGENT RELEARNING ON THE PERFORMANCE OF THE SPATIAL TASKS]
Abstract:
Introducing of urgent relearning in radial maze, consisting of one or two shifts of reward position in raw without any gap between behavioral sessions, resulted to inability of animals to use optimal navigational strategy to find preferable reward in maze while keeping responding to int-ra-maze stimuli. Procedural introducing of time-out between tested behavioral sessions, which was accompanied by sleep generated naturally or induced by injection of neuropeptide ACTH 18-39, resulted to considerable improvement of relearning in radial maze as well as reducing per-severative behavior and attempts to refuse from responding. The data obtained demonstrate the important role of sleep for successful urgent relearning in radial maze and preventing possible neurological disorders.
