Chemical transfer of learned behaviour: No specific effect observed in rats trained to swim either of two mazes

Summary

There has been a recent report claiming the successful transfer of detailed spatial information about a maze by injecting brain extracts of trained mice into naive recipients. We have repeated this experiment with rats using a swimming maze as a precaution against odour cues. No evidence for information transfer has been obtained under these conditions.

Zusammenfassung

Kürzlich wurde über ein Experiment berichtet, in dem es gelungen sein soll, die spezifische räumliche Repräsentation eines Labyrinths durch Gehirnextrakte von dressierten Mäusen auf Empfängertiere zu übertragen. Wir haben das Experiment unter Ausschluss von Geruchsspuren (Schwimmlabyrinth) an Ratten wiederholt und dabei keine Informationsübertragung nachweisen können.
