Environmental toxin Bisphenol A can affect newborn brain
Date:10/26/2011

olychlorinated biphenyls (PCBs), and DDT.

In an entirely new study these researchers examined whether exposure to Bisphenol A during the neonatal period can cause permanent damage to brain function. In the experiment different doses of Bisphenol A were given to mice when they were ten days old. The mice underwent a so-called spontaneous behavior test as young adults, in which they were made to change cages from their well-known home cage to another identical one during one hour. Normal mice are very active during the first 20 minutes, exploring the new home environment. This activity declines during the next 20 minutes, and in the final 20 minutes it drops even more, and the mice settle down and sleep.

"In our study we found that a single exposure to Bisphenol A during the short critical period of brain development in the neonatal period leads to changes in spontaneous behavior and poorer adaptation to new environments, as well as hyperactivity among young adult mice. When this is examined again later in their adult life, these functional disturbances persist, which indicates that the damage is permanent and do not in fact disappear," says Henrik Viberg at the Department of Organism Biology.

Using the same behavioral method, it was also examined whether the individuals that had received Bisphenol A during their neonatal period reacted differently than normal individuals to adult exposure to nicotine, which would indicate that one of the brain's most important signal systems, the cholinergic signal system, was affected. Normal animals exposed as adults to the given dose of nicotine experience dramatically increased activity compared with animals that were not exposed to nicotine. Animals that had been exposed to Bisphenol A during their neonatal period and then received nicotine as adults did not evince the same hyperactivity as normal animals at all. This indicates that the choligernic signal system had been affected and that these indivi
