| Abstract: | A pronounced sensitization phase was observed on low-frequency stimulation of hippocampus slices from rats decapitated immediately
after training to a conditioned bilateral escape reflex. The same effect was recorded in slices from control animals after
brief application of serotonin. Serotonin had a significantly smaller effect on the electrical activity of trained animals.
Changes in the efficiency of the serotoninergic input to hippocampus neurons are suggested as one of the factors eliciting
low-frequency facilitation in trained rats.
