Researchers show low BPA exposure can alter memory in adult rats

Scientists have shown that exposure to a low dose of bisphenol A (BPA) can impair memory and alter brain structure in adult male rats.

The researchers exposed the animals to a single dose of BPA at a level just below the reference safe daily limit recommended by the US Environmental Protection Agency (EPA). The results showed BPA significantly impaired both visual and spatial memory, which may be caused by changes in specific brain proteins and cells involved in learning.

The authors conclude their results indicated developmental exposure to the chemical may affect neural plasticity processes in the adult brain.

The research is published in the journal Behavioural Neuroscience.
