Memory Recorded on DNA? The Ground Level of Learning

Interestingly enough, it may be that memory is stabilized by alterations in the DNA of particular neurons. This article argues that the DNA in neurons involved in a particular memory are altered through a process of "methylation," which basically means that a tiny CH2 molecule is "snapped" on to nucleotides of particular genes to get the neuron to "remember." (Sorry, I was a bio chem major undergrad for a long time.)
