Study sheds light on molecular encoding of memory

A new study supports the idea that chemical tagging of DNA – a process known as DNA methylation – may be how memories are encoded in the brain.The study shows that epigenetic changes involved in memory formation also occur in non-neuronal cells. The study, by researchers from the German Center for Neurodegenerative Diseases (DZNE) in Göttingen and Munich, is published in Nature Neuroscience. There is still a lot we do not know about how the brain deals with memory and learning – the ability to draw conclusions from memories. A widely held theory is that memories are encoded by changing the connections between brain cells. This is the idea behind brain “plasticity” – the way the brain changes through life. The forming, strengthening and weakening of the connections in the…
