BACKGROUND There is uncertainty whether environmental levels of exposure to polychlorinated biphenyls (PCBs) adversely affect mental and motor development in early childhood. We aimed to establish whether such an effect is of only prenatal or additional postnatal origin, and if a favourable home environment can counteract this effect. METHODS Between 1993(More)
The central nervous system is one of the target organs for polychlorinated biphenyls (PCBs). We measured the effects of maternal exposure of Long-Evans rats to a mixture of PCB congeners reconstituted according to the pattern found in human breast milk (reconstituted mixture, RM) on long-term potentiation (LTP) in two brain regions.
