title: [Modulation of the long-term memory by delayed administration of the nootropic agent L-pyroglutamyl-D-alaninamide during spaced and massed training of rats].
abstract: L-pyroglutamyl-D-alanine amide significantly enhanced freezing response in the group of rats with massed training and reduced it in the group with spaced training. The control animals revealed a higher freezing response with the spaced training. No differences occurred between the groups in a cue test.
