title: [Restoration of long-term potentiation by food delivery to deprived rat].
abstract: The possibility of restoration of the extinguished long-term potentiation at the Shafer collaterals projections in food deprived rats to small amounts of meal was studied. Giving a small portion of meal restores a population spike's amplitude for the first CA1 response to paired-pulse stimulation. The amplitude of the population spike for the second response restored completely. Giving a small portion of meal in control groups of deprived animals without preliminary acquisition of potentiation did not produce changes of the CA1 evoked responses. Restoration of potentiation in the described experiments is likely to be related with a certain level of animal's emotional tension. It is assumed that a restoration of potentiation at natural conditions could be necessary for solution of tasks related with satisfaction of biologically important for animal needs.
