While there were no group differences during acquisition of VDL in the Lashley jumping stand, a pronounced retention deficit was seen both in maternally and permanently exposed rats. This agrees with the results from the RAM where no difference was detected between the effects of the two exposure regimens. Thus the neurobehavioural deficit seen in adult animals is not aggravated if exposure continues into the post-weaning period, and until adulthood. At least to 400 days of age no recovery was detected in maternally exposed rats. In monkeys, likewise, sustained behavioural impairments have been reported after an exposure-free interval of 5 years (Levin and Bowman, 1986). 

Lashley jumping stand A device for testing visual discrimination learning. Two patterns are simultaneously displayed on two different doors and the one with the false pattern is locked. The rat has to cross (originally to jump) and pass through the door with the correct pattern to get a reward.
