New research: single low dose of bisphenol #BPA impairs memory in adult rats

Adult male rats exposed to a single dose of the contaminant bisphenol A (BPA) had trouble remembering an object's look or location after only a couple of hours, according to a study published in Behavioral Neuroscience. Researchers also found changes in brain proteins and cells involved in learning and memory. The part of the brain cell – called dendritic spines – that allow cells to talk to each other were less dense in the memory regions of the brain after exposure to BPA. The study specifically measured memory consolidation – the first process of remembering where an experience is converted into a memory. This is one of the first studies to measure the effects of a one-time, low dose BPA exposure on memory processes and brain cell formation in adult males. The results echo prior studies that also find BPA impairs memory. Although an animal study, these results suggest t...
