If it is true that epigenetic changes to genes active in certain regions of the brain underlie our emotional and intellectual intelligence — our tendency to be calm or fearful, our ability to learn or to forget — then the question arises: Why can't we just take a drug to rinse away the unwanted methyl groups like a bar of epigenetic Irish Spring?
They used a somewhat bizarre technique in which two mice were sutured together in such as way that they shared a circulatory system (known as parabiosis), and found old mice joined to their youthful counterparts showed changes in gene activity in a brain region called the hippocampus as well as increased neural connections and enhanced «synaptic plasticity» — a mechanism believed to underlie learning and memory in which the strength of neural connections change in response to experience.
Genes in these regions warrant further investigation to uncover the biological processes underlying the condition.
In the present study, to elucidate the neural mechanism underlying this behavior, we used an immediate early gene (IEG) to map the active brain regions of Japanese honeybee workers during the formation of a defensive bee ball.
Remarkably, 30 regions were each found to contain a single gene, facilitating the identification of candidate genes underlying reproductive isolation.
