Microdialysis administration of vasopressin into the septum improves social recognition in Brattleboro rats

Engelmann, Mario, Landgraf, Rainer·1994·Physiology & Behavior

Abstract

The role of septal arginine vasopressin (AVP) in a social recognition test was investigated in both homozygous Brattleboro (HO-DI) and normal Long-Evans rats. To do this, the duration of investigation of conspecific juveniles by untreated adult males of both rat strains was measured before and after inter exposure intervals of 30 and 120 min. Additionally, a microdialysis administration technique was used to administer synthetic AVP (0.2 or 2.0 ng) or its V1 receptor antagonist d(CH2)5Tyr(Me)AVP (5.0 ng) into the mediolateral septum concomitantly with the behavioral test. Untreated HO-DI rats showed an impaired social recognition compared with untreated Long-Evans rats. A similarly impaired performance was observed after V1 receptor antagonist treatment of Long-Evans rats. Microdialysis administration of synthetic AVP, on the other hand, significantly improved social recognition in both rat strains. The data suggest that endogenous AVP in the septal brain area is critically involved in the acquisition, storage, and/or recall of olfactory cues in rats.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
