Maze performance of mature rats recovered from early postnatal infection with Murray Valley encephalitis virus.

Abstract

"Rats which were inoculated intracerebrally with Murray Valley encephalitis virus when 8 days of age were, as mature animals, unable to master a rather complex maze. Only 1 of 29 had an errorless run after 15 trials while 38 of 50 controls had mastered the maze after the same number of trials. Rats which were 10 days of age when injected with the virus also demonstrated a learning deficit, but it was not as marked as in the 8-day-old animals. The virus did not definitely affect the ability of rats 14 days of age or older to learn the maze." From Psyc Abstracts 36:01:1DJ75D. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
